Colorsound Tremolo

Soo easy. Rate and depth controls, solid on/off footswitch, input and output. All you need! All great quality and very comfortable layout for live use due to the big long casing.
The only down side is that is made without a power input and you have to remove the whole base to access the battery. But I solved this in 1 minute by attaching a reversed battery clip power cable from my multi 9V DC power supply (daisy chain). Simply filed a little hole in the end of base plate for the cable and it now has a power cable!

I LOVE IT!!! Lets be frank straight away...this is very vintage sounding and operating effect. NICE BOYS NEED NOT READ ON! It's bold and quirky (and Purple)!It has one sound and only one style of tremolo, so if it's not what you're after it's useless. But if you are after the harsher square wave tremolo sound such as on a Vox AC30, I'm sure you will love it as much as I do. Loads of character.
With the depth control at maximum it simply chops your signal in and out, there's no smooth fade up and down. Bringing the depth control down gives you more non effected signal and less "tremoloed" (is that a word?) signal. I like it around 1 o'clock for subtle vintage trem sound. But bringing it up to max can give a really cool chopping chopper effect.
The speed control simply controls the the rate of the tremolo oscilations. The range of speeds isn't huge but it's in the perfect zone for musical use.
This pedal is all anologue, true bypass and hand wired with very few components. It is not noisy at all in my setup (I have it after my drive pedals and before my delays which is pretty standard). Is does cut a really tiny bit of signal when on, but as it's a tremolo that dips your volume this means nothing! ( I actually like that).
Sound QUALITY is excellent!
In short it can go from classic Vox subtle tremolo sounds, through surf stuff, into to that Tom Morello chopping effect.
OH YEAH...IT LOOKS SOOOOOO COOL!

For all you gear geeks, I'm mostly using a customised Burns guitar with vintage strat pickups, through a Tube Screamer, Proco Rat, MXR Micro Amp, COLORSOUND TREMOLO, EHX MemoryMan, and into my beautiful 1968 Fender Bassman Amp (silverface with blackface wiring)

I havnt had it long but seems extremely reliable. Big solid metal chassis, and all components are high quality and robust. Hardly anything inside to go wrong, but if it ever did, could be fixed so easily! Also the simplicity means it's easy to modify.

Purchased second hand. But Colorsound no longer exists so I presume there is no customer support available.

It's great! Has limited appeal and use, but if you love quirky, high quality vintage gear and like to be a bit different, you'll love it.
Classic vintage, anologue tone and tons of character!

two knobs....depth and rate....could hardly be easier.

sounds really good....you can nail rolling stone's gimme shelter intro easily...or riders on the storm by the doors....the effect is very clean and warm.....in one word VINTAGE (so it does what it says).

seems dependable....there are very few components inside...so i don't see what could go wrong.

you get classic vintage warm tremolo......there coud be more features but it's a reissue..soooo......
tone is just in it, and that is what counts.

Simple 2 knob layout. (Speed, sweep, and on/off).

I use it with non tremolo amps like Tweed Fenders and a Marshall JCM800. It's quiet and it can be adjusted from a slow throb to a fast helicopter chopping sound.

This is a VERY simple design. Opening it up reveals a circuit card that only has about 7 components on it. I see very little that could go wrong.

Never dealt with Colorsound. But the simplicity of their pedals probably don't require many service calls.

I use this effect when I play electric slide blues (ala Ry Cooder), on one of my non-tremolo amps. I don't care for the high speed end of the spectrum, but the slower speeds give a nice organic sounding throb to slower tunes. The only thing that I find strange is that the pedal is the size of a BRICK, but the actual electronics could fit into a MXR sized mini pedal. The only things I don't like are that there's no battery door to access the battery, (you have to unscrew the case to get to the battery). And also that there's no AC power option. But I guess this pedal is a reissue of the old 60's/70's effects that only ran on battery. Overall it's a good pedal that can produce a warm tremolo vibe for your non-trem equipped amps.
