Fuzz MKIII / MKIV

 

ARF72 Fuzz GE MKIV .3 Limited (Vero)


Life’s about changes, about taking decisions all the time, most of the times for the good of the people around you, or your own luck.
Well, I know, making a Tonebender MKIII built in veroboard is mental, finished three units and they been listed on eBay, reverb and the Rhodium Electronics blog. 


Limited and exclusive latest series. Therefore, will continue with the series ARF72, using same components, but it will be designed in a professional prefabricated PCB in future, as per ToniBender MKIII boards, but mini version. 



ToniBender MKIV germanium Russian mix according to Rhodium Electronics selection. “Tone to the bone always!”


ToniBender MKIV Fuzz circuit built in veroboard, this new ARF72 based on a germanium selection of four number of Russian transistors.


Top mounted jacks. Output gain control at rear of the desk enclosure increases versatility and dynamics responses of the sounds. 



This new ARF72 Fuzz Tonebender built in veroboard with audio grade electronics in Lo-Fi version.


Only three units small run, hand built one at a time.

PROTOTYPE VEROBOARD ARF72 MARK IV .3

Designed to opened from upper cover, side screws to disassembled in order to get access to the battery. 


True bypass and only battery working unit, with power isolation in the input jack.



RHODIUM ELECTRONICS TONIBENDER  MKIII FUZZ


ToniBender MKIII shown in this picture is prototype no.1 of a serie of three prototypes in order to develop this new version of ToniBender Fuzz MARKIII, following with a super limited standard series.
 

Limited Gold Edition Tonibender MKIII Fuzz.


Rhodium Electronics ToniBender MKIII Fuzz take on the legendary ToneBender MKIII and MKIV circuits, setup with germanium transistors and a selection of vintage and audio grade electronics.

Version 2 of the ToniBender MKIII built in professional prefabricated PCB, more of a robust and reliable construction for effects pedals in a big enclosure type.
 
Three internal user trimmers, so in order to dialing output signal amplitude, and biasing final amplification stages of this Tonebender circuit layout. 
 
It runs with 9 volts battery. Super limited series in hammered gold. 
 
 


This is the second version of this ToniBender MKIII with a different setup and more of a consistent fuzz tone and sustain, with more of a tonality range and reliable dynamic response for guitars.

Version 2 of the ToniBender MKIII built in professional prefabricated PCB, more of a robust and reliable kind of construction for effects pedals in big enclosure types. 




Three internal user trimmers, so in order to dialling out signal amplitude / gain, and biasing final amplification stages of this Tonebender circuit layout. Modification based on leaking bass frequency to the ground from output volume control. It runs with 9 volts battery. Super limited series in hammered gold.


ToniBender MKIII Camden Records Revision

Finishing with some units were in the shelves, previous runs sold very quick, now I had time to troubleshooting and demoing them one by one.
 

This time using the dirt channel of my Marshall DSL-1 in economic mode, gain level 1 or one and a half, maximum volume, economic just about 1 watt, it’s like attenuator, playing with bridge pickup, demo with neck pickup next.


Two Units only with chicken heads.

Last ToniBender setup with this configuration of transistors was labelled with a Camden Records logo on top front, but it response vary a little from one to another, due to the selection of transistors and their features, values like gain and leakage, in the last revision.





Discovering a new umbrella of possibilities and guitar tonalities, these variations still exposed to an internal user trimmer, which it’s setup at maximum output gain by Rhodium Electronics. 


Our customers mentioned Foxx Tone Machine, Fuzzface, Zonk Machine, of course ToneBender, and it’s incredible the amount of nice words and feedbacks received.

 

 TONI-BENDER MARK III Version 1

Rhodium Electronics Fuzz ToniBender Mark III. This is a small run and have no logo, there only few units available online, as per ToniBender MKiV been tweaked to allow using contemporary germanium transistors.

Rhodium Electronics take on the VOX Tone-Bender MKIII lately modified by Solasound according to different biasing for MKiV and Batman versions, which them been prototyped by Rhodium Electronics in London. 

Biased according to a standard gain setup with very low leakage vintage soviets transistors and a selection of audio grade electronics components.

Tone-Bender Mark III version is more of an early rock vintage sound, with more of an unitary gain and more guitar volume control and stable tonality range.

 

TONI-BENDER MARK IV Version 1 

Tone-Bender Mark IV is more of a consistent fuzz, higher output gain than previous version of the Tone-Bender Mark III. 

It responses very good when roll off from guitar volume knob, so these very low leakage germanium transistors been biased according to standard specifications, but still can not clean signal up as per a Fuzz-Face or Tone-Bender MKIII circuits.

Messing around a Telecaster Japan Squier 90’s and TONIBENDER Mark IV. Finally decided this setup for assembling our latest fuzz prototype.


Loved the responses with Mullard OC44 OC71 and OC74, finding sonic treble that didn’t come up with other transistors. So, smashing job! Achieving a right good FUZZ TONIBENDER MARK IV. Second Round Mullard AC128 Red Dot 🔴 for Mark IV Tonebender Fuzz Testing and Troubleshooting...Third Round Mullard OC81 White Dot ⚪️ for Mark IV Tonebender Fuzz Testing and Troubleshooting...
 
 

 
Sixth round and turn for first NKT222 transistor of the day... Fourth Round Texas Instruments 2N527 transistor for Mark IV Tonebender...


Seventh round back to Mullard OC74... Eight Round Mullard OC71 glass specs TONIBENDER Mark IV... Ninth Round Mullard OC44...
 
 

TONIBENDER MKIII TOUR FUZZ BOX

UK TOUR FUZZ BOX ENDED - 
TOUR FUZZ BOX TONIBENDER MKIII - SOLD OUT


Guitar Demo TONIBENDER Mark IV Compact




Messing around a Stratocaster Japan Squier early 80’s and TONIBENDER Mark IV.

 
 
Finally decided the same setup for the third transistor, as per the book, so I didn’t want to spend time to setup a bias, lucky we had a few transistors for testing this circuit.


You can check it out on my personal Facebook and Instagram. Recently created www.tanquelab.com confounded company with the best tooling mastery engineer, my cousin Jose!


Recently built this preordered Toni-Bender MARK iV with a couple of replicated TONEBENDER pedals with different specs and bandwidth.
 
 
This is 2/2 and demoed with Solasound Colorsound Wah Fuzz Swell from blues rock to psychedelic flamenco. Recorded with a Fender Stratocaster Japan Series E Kahler tremolo bridge and Laney amplifier.

ToniBender MKIV Compact Desktop 


Compact version 3 of the ToniBender, which it would not used in my own, so I did this one as part of a deal with a friend, so it’s special, it’ll be repeated with Mullard OC71S and adding an input impedance control at the rear panel. Output transistor POIF OC45 and fourth transistor as a diode.


Output gain control at rear of the desk enclosure. True bypass and only battery, with isolation in the input jack.


Germanium Tonebender MKIII tweaked for leaking bass from output volume control. Clean up gently when roll off from guitar volume.


Internal bias for stage 1 and 3 of the amplification circuit. Carbon trim pots. Wima and tropical fish and Vishal and Phillips and Sprague capacitors.

Setup with Mullard British Made OC71s and a selection of audio grade electronics components. Working in a new Compact ToniBender MKIV with original British Mullard OC71s for my friend, who also purchased a multimeter, to get references of the collector bias values when some some nice tone and spots of old songs playing with the ToniBender MKIII version 2, which it still in a tour box in the UK, thanks Terry!

Based on previous prototype Compact version 3 of the ToniBender, which it would not used in my own, so I did this one as part of a deal with a friend, so it’s special, it’ll be repeated with Mullard OC71S and adding a input impedance control at the rear panel

Germanium Tonebender MKIII tweaked for leaking Bass from output volume control. Clean up sweetly when roll off from guitar volume knob.

Internal bias for stage 1 and 3 of the amplification circuit. Carbon trim pots. Wima and tropical fish and Vishal and Phillips and Sprague capacitors.


ToniBender MKIV family friendly pedal, compact desktop box to sit on top of the amp and enjoy those tones from sixties and seventies, a similar thing in a similar range, but still different.


Tweaked to reduce bass frequencies when decrease volume control.


Cutting the mix easily than a simple master volume. Internal trimmers and stuff, do not touch it!
