Buffer / True Bypass Switch

From the factory we ship the Echorec in "buffered" or "trails" mode. (It's not really a buffer, it's a juicy preamp, but non-true bypass mode is
commonly called "buffered" mode. You will be able to run long cables without signal loss though in this mode!)
There are a couple of good reasons for keeping the Echorec in this mode:
Trails! That means when you hit bypass whatever was echoing gets to keep echoing until it naturally decays. Or if you have the Swell control
cranked up to self-oscillation levels, that'll keep going indefinitely, but any new playing you do after hitting bypass will not be echoed. You
don't lose the illusion of ambience and can smoothly make the scene change transition.
The Echorec's preamp! It enhances your guitar signal, and gives you better playing feel with increased dynamic touch sensitivity. Plus, via the
Gain trimmer you can have a preset amount of boost always on if you want. More about this in the Gain trimmer section.
Or you can flip the internal switch to "true-bypass" mode. This is a hard wire bypass that bypasses all internal circuitry.
While we think you'll always want to leave it in trails mode, there IS a cool reason to use it in true-bypass mode: You can set the Gain trimmer
for a pre-determined amount of boost so when you hit the Echorec, your sound will get louder, juicier, echoier, and have more impact. Great
for emphasizing certain passages or for epic leads.

Adjusting the Internal Trimpots

The Echorec has two internal trimpots that are set for optimal performance from the Catalinbread factory. Being set and forget type controls,
we put them inside. When adjusting trimpots, it is important to recognize that you must use the correct tool for the job and do very careful
work. Trimpots are much more sensitive to adjustments than the knobs on the outside of the pedal. Use a #00 Philips screwdriver, make sure
the tip is seated correctly and only make 1/8 turns at a time. If the the trimpot doesn't seem to move, it is at it's full rotation. Do not attempt
to force it beyond these full clockwise and counterclockwise positions or you will destroy the trimpot.

Internal Controls - Modulation amount

This trimpot is at the top left of the circuit board. This pot adjusts the modulation depth. From the factory we ship the trimpot set to 1.00-1.1V
DC. This is the optimal setting for the modulation to create a circular illusion of the recording drum without getting too cartoon-like. You may
however wish to dial it back or crank it up, depending on taste. Overall, the modulation range of the trimpot is intentionally narrow, we're
confident the position that it ships in is ideal, mimicking the rotating drum warble effect of the original. If you feel the need to adjust it you
can always return to the factory spec with the aid of a multimeter. The modulation is applied to the repeats only! Your dry signal remains,
um, dry.
