CSound Tremolo

Another lovely wobble box, this time getting somewhere close to the throbbing goodness found on a vintage Vox amp.

Simple build using using modern, more available parts than the vintage original, but sounding exactly the same. Pot values and tapers have been fiddled with for a much better range and sweep too.

Supposedly the favoured trem of Phil Manzanera, and used by Mr Bonnamassa (apparently), so what's not to love?

Board-mounted pots for minimal wiring and easy enclosure mounting.

If you want the PCB without parts there's a link for that at the bottom of the page.

Partial kit: PCB, all board-mounted components, pots.

Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.

Enclosure (pre-drilled) is available as an option with full kits, and can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included.

Builds are only available with full kits including enclosure and vertical-mount pots. Please choose appropriate knobs.

Another winner from the Fuzzy Dog
"An excellent little kit and circuit which makes very pleasing tremolo. I particularly like the high degree of tonal transparency and minimal sense of volume loss at the subtler settings which is what I ll be using. Thanks Fuzz Dog" David - 05 March 2022

CSound Tremolo
"Having built several FuzzDog pedals and with very little consideration the C-Sound Tremolo is an absolutely outstanding effect that does exactly what it says 'on the tin'. I really didn't want another Tremolo but however, this one completely surpasses the three branded tremolo pedals that I already have. The circuit easily fits into the 1590B enclosure that was intended for a MagicVibe that just isn't going to work out for myself. My C-Sound (a take on the famed Color Sound tremolo) is true to the build sheet, no mods or pulsing LED, just a nice easy two knob build that works really well towards the end of the chain. Nice things happen when used with a single knob Phase 90, both of which would score my 4.5 to 5 out of 5

First build - C Sound Tremolo
"This was my first pedal build, and with lots of checking and double checking it went fine. The tremolo does the Johnny Marr How Soon is Now sound perfectly! Thanks." Steve A - 06 December 2018
