it’s possible the 2880 is built without the discrete compressors and limiters that its Boss counterparts have. It’s possible it’s not designed to be clipped out. and it’s possible no one wants to be told to turn down.
if it’s really a big deal, throw a gain pedal [or two] afterwards, an EQ or an LS-2 or a clean boost or something.

did you try it with the sliders turned up higher? they only work in a reductive sense- you can’t make something louder than the initial volume with them. so max them out.

Barber Direct Drive.

when not muted, the LED-scale provides a sample-and-hold control voltage out, for all those EHX pedals that can have cv ins?

the POG is a polyphonic octave generator. It’s a pitch shifter with low-pass filter and detune.

Go with EHX. I mean, the Pulsar and Neo Clone are far better than the competition and then the DEM and mxr flanger are pretty close, circuit-wise. The only one that you might have a better chance with MXR on is the phaser – and even then, it’s probably going to be cheaper to go with the offbrand version. I mean, they’re both just four stage phasers but deciding whether you want an ‘intensity’ switch or a ‘feedbacks’ switch is really the difference.

digital, and the manual should be more or less the same as the current model Nano Holy Grail. Only thing to watch out for is to use the stock power supply, otherwise there’ll be hum.

have you ever tried to get Boss’s customer service department? I can call EHX whenever and talk to a real person. Good luck doing that with Boss/Roland

you’d have to program the dsp [an FV-1, if you’re going to look up how to code] to do that. a which point it’s probably better to just go get a pitch shifter.
There is a mod to get a chorus/flange effect and a delay + pitch shifter though. just google holy stain fv-1 and there should be a few forums it’s discussed at.
