[Harp-L] Digitech RP 355 Troubleshooting Assistance

[Rich Eisenberg]

I have been playing Special 20's using a green bullet with a hot CM
element, a Lone Wolf Harp Octave, and a Boss DD 3 Delay (both dialed down)
into a modded Epiphone Valve Junior. People like the tone.
I recently purchased a new Digitech RP355 and loaded the Huntersounds Patch
Set into it. I like the Huntersounds patches, and am learning how to use
them.
The problem I am having is with the RP 355. The first time I took it out
to an open mic, it operated fine for a bit, then froze up on one patch and
wouldn't change.
The next time at the open mic it worked for an hour, then re-set itself to
the factory settings.
Does anyone have any thoughts about addressing these issues?

Thanks.
Rich

This is unusual behavior to say the least. If the following doesn't fix it, I recommend that you send it to the nearest Digitech repair center.

First, do a factory reset and then update the RP to the latest firmware (I think it's version 1.4) if you haven't already.

it's possible that what's happening is either 1) your power supply is going bad, or 2) the power in the places you're playing is flaky, either of which could make the chips in the 355 go a little bonkers. I think the former is more likely than the latter. You can test it by taking your RP to the nearest instrument store that stocks Digitechs, borrowing a new power supply, and playing through it for a little while. If that solves the problem, get a new power supply (about $25). Also, check the tip on your power supply cable (the end that plugs into the RP). If there's a red band at the tip, cool. If not, replace the power supply.

You could also try getting a power strip that regulates the power to the device. Those cost about $80--I really think any electric musician should have one. Flaky power causes lots of problems, not to mention occasional electrocutions.

If all else fails, send to digitech for repairs. also check with Digitech tech support at digitech.com, right away. they may have an immediate diagnosis, and they're very easy to deal with.

Two fails on two trys with a brand new unit? I would contact Digitech about replacing it. I've had an RP 155 for 2 years now and not one glitch. Huntersounds are also on mine. My only problem has been trying to record to computer through the USB, but I think it's my computer or the Audacity program I'm running since the RP works just fine with either of my amps (or even both at once).
