Fulltone Custom Shop SupaTrem 2.

Why are there so many multi-function modulation pedals popping up?

Because there's a DIGITAL SOUND PROCESSING chip (DSP for short) pedal makers use creating the effect that costs about $1..that's why.

I don't use DSP chips because I prefer ANALOG, I guess I'm old fashioned and I don't want my great sounding guitar signal converted to digital by a budget Analog-to-Digital Converter running on low voltage, processed with a $1 DSP, converted again back to analog with a budget Digital-to-Analog converter on the way out the pedal. It all Sounds too cold and I can feel them because budget A/D & D/A converters track poorly. Now think of that process happening again and again if you have multiple DSP pedals.

The Supa-Trem has been an extremely successful pedal for me over the last 15 years, partly due to the TONE of the circuit, which has a very good sounding JFET amplifier at its heart.

Another key ingredient has been the Fulltone Opto-1 photocells that I designed and have made...they have the optimal resistance range, as well as the correct rise and fall times for all speeds required for a great Tremolo design.

A while back I started wondering what would happen if I took two completely separate Supa-Trem circuits and joined them together! Not fake-stereo like other Tremolo, Chorus, Phase, Flanger, etc pedals which simply invert the signal at the output and send it to another jack. Two identical circuits in TRUE-STEREO with two INs and two OUTs!
