RHODIUM ELECTRONICS FUZZ TONIBENDER MKII
REVISION 1.5 GERMANIUM NKT275
These series of fuzz pedals will available soon with a run of four initial boxes engraved by hand, according to develop a next standard series based on NKT275 transistors. A mini fuzz pedal version, looking to offer NKT275 fuzz to the amateur players and musicians in general, without breaking the bank.
A tweaked circuit to achieve the right tone for these peculiar transistor NKT275 specifications. It travels from Vox ToneBender to Fuzzface and Zonk Machine tones, allowing more bass will lead you to the Schaller Fuzz range and others fuzz distortion.
This new version will be available soon, with engraved enclosures and same family of transistors NKT275, giving the name to this fuzz pedal AR275.
FUZZ TONIBENDER MKII REV. 1.5 RUSSIAN GERMANIUM
New circuit layout based on Russian germanium transistors, more of a Vox Tonebender MKII reissue sound with two germanium transistors, tweaked to allow more of a consistent fuzz signal and tasty tones for a modded fuzzface circuit.
This is a ToniBender MKII revision 1.5 by Rhodium Electronics. Germanium Russian Transistors selected pair hFE 60/80 low leakage, setup with internal biasing trimmer, which would take your tone from fuzzface to tonebender, Zonk machine and Schaller fuzz tones, and corresponding dynamic responses with this family of germanium Russian transistors.
This is an early prototype series, first batch of two units with Russian transistors, previous a bigger run of fuzz pedals coming soon with similar specifications setting up NKT275 transistors, and this current family of equivalent Russian transistors when required. This unit works with a PSU 9 volts negative centre. Battery free pedal, still setting a battery snap inside enclosure.
Reserves are open for the next batch of pedals with this circuit layout. It's a new revision of the AR275 PCB board. Pre-order ARF66 now available only by email or blog contact form.
An exclusive edition, super limited Fuzz pedal with NKT275 transistors, awesome and affordable. ARF66 will be available from next year 2022.

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.

Rhodium Electronics Classic Fuzz Prototype
This Fuzz classic silicon Fuzz-Face layout with mods by Roger Mayer is built with BC109 transistors. This model was a summer 2020 pre-order, a low cost silicon version of the Band of Gypsys recently launched on the market. Our customer wanted to try ordering us a pedal, instead of buying the new band of gypsys pedals on market.
We did our best to research about the sound from these three concerts and developped our own version of the sound from this album of Jimi Hendrix, following the different layouts, and using transistors from our own stock, instead of the MPSA silicon transistors used from famous brands, which are very high gain, but noisy and have a different frequency response than our unpredictable BC108 / BC108B / BC109 collection of silicon transistors. 
During the days this preorder was received, we were developping a few ToneBender MK IV pedals, but finally decided to attend to a profesional studio with our latest Fuzz Silicon version.
After the Jimi's Fuzz didn't replicated any other silicon transistors fuzz, and this unit sound so good, so had to change the plans, contacted Camden Records in Camden Town, London.
They contacted to Javier Amaya, current guitarrist of The Grudge, and absolutely a Stoner Metal Master. The demo was recorded in the evening and enjoyed a lovely time exploring different sounds an settings with the Orange amplifier, and custom Gibson Les Paul and Fender Stratocaster guitars.
Thanks to this preorder from Terry, our customer, guitarrist Javier Amaya loved our silicon Fuzz BC109, so we decided to make a small run of Band of Gypsys pedals and gift to the guitarrist, and friend with a special version of this pedal in hammered sparkling red and white knobs.

The secret to find the tone with this circuit is the amplifier to used.
In this case, the secret of my customer, and better musician, was a recording made with a Valvetone 5 Watt amplifier through a Celestion Vintage 2x10 Cab.
I studied this recording, but the standard circuit is critical, and the original setup five capacitors. Valvetone amps are Australian made amps, sometime called EB amps. I did this demo with a Laney, whilst in the new EHX nano version official demo I think they used a Blackstar amp or similar.
One of those preorders that requires the audition of samples and research tone.
This a replica of the Muff Fuzz by EHX in the early 70’s opamp version.
Our friend in the Land of Oz wanted a standard copy of the circuit, which following different resources and genuine pieces as pictured, found it has a five capacitors in it layout.
We tried to replicate this early 70’s commercial version with alpha switch and potentiometer, in veroboard as requested to keep a 70’s minded engineering, and standard Mylar and low ESR electrolytic and Farnell 1N4148 diodes based on opamp NEC Japan c4558c.
