Effect pedal repair?

Hey there, I've got a Zendrive and I recollect information technology has a chip is diddled, it lights up but no audio output. I've tried calling around in my expanse, Denver metro, but then far I oasis't been able to locate anyone who does those sorts of repairs. I emailed Hermida sound a few days agone and I've yet to hear back from them. Does anyone know where I can send it out to become diagnosed and repaired? Any feed back would be capeesh, thanks.

• #3

Cheers, I just sent them an e-mail. It would be overnice to discover a shop or person who does that kind of piece of work locally, but perhaps that's non possible.

• #iv

I would think that anyone that repairs amps would be able to look at it. The schematic is available, and often a visual can observe the bad part.

There'south a few things you can practise to start the trouble shooting process... "chips" are fairly rare points of failure. In lodge(ish):
Switch
Pots
Jacks
Bad solder
with components coming up a afar 5th.

I've had several Lovepedal Hermida pedals that didn't work, or worked desperately because of missing or cracked solder, and so if you can borrow a soldering iron, you could only impact all the joints to make sure they've flowed properly. And if at that place's a pad with a component sticking thru but no solder, and then you or someone else could solder that.

You could use a wire with alligator clips to bypass the switch. Or a continuity tested to check the switch. They can be cleaned or hands replaced.

Yous can make clean the pots with Caig Deoxit (skillful to have some on manus) and shoot some into the jacks as well.

Too worth trying both a battery and a power supply as sometimes that can be a problem.

If all that doesn't clarify things they you'll accept to send it away. Hermida Audio is closed since the early teens. He partnered with Lovepedal who built the Zendrive for about 5 years before closing shop in early 2022, no signs they're coming back.

I've had several Lovepedal Hermida pedals that didn't piece of work, or worked desperately because of missing or cracked solder, so if y'all can infringe a soldering atomic number 26, yous could simply touch all the joints to make certain they've flowed properly. And if there's a pad with a component sticking thru but no solder, then yous or someone else could solder that.

You could use a wire with alligator clips to bypass the switch. Or a continuity tested to check the switch. They tin exist cleaned or easily replaced.

Y'all can clean the pots with Caig Deoxit (good to have some on hand) and shoot some into the jacks also.

Also worth trying both a battery and a power supply as sometimes that tin be a problem.

If all that doesn't clarify things they you'll take to send it away. Hermida Audio is closed since the early teens. He partnered with Lovepedal who congenital the Zendrive for about v years before closing shop in early on 2022, no signs they're coming back.

I didn't realize that Hermida closed up shop, I emailed them first and it's no wonder they haven't replied back, thanks for informing me. This was probably my fault as far every bit the pedal goes, the transmission said it could take an 18v adapter which I had one laying around. The specs all looked proficient and seemed to match the requirements so I plugged it in, I then heard a very slight zap....no! I hadn't all the same fifty-fifty turned the pedal on, I hit the switch and it lit up and then I thought whew I got lucky, simply no that wasn't the case unfortunately, no sound output. So I'm quite pissed at myself and but want to go it repaired, hoping it's just the ic chip. Alchemy Audio emailed me back and said they'd try to repair it. I called around to quite few amp and guitar repair places locally and nobody seems to practice pedal repair. I don't really want to try it myself and further muck information technology up every bit I have no experience doing that kind of work. I guess I'll bump this one more than fourth dimension and if nobody chimes in with a local store I'll ship it off to Alchemy Audio and hope it can be salvaged. Thank you for the recommendation by the manner SlaminSam.

Information technology won't be the chip, bold the protection diode did it's job that would exist the component to be replaced.

• #8

Information technology won't be the chip, assuming the protection diode did it'south chore that would be the component to be replaced.

So you recall it would be the protection diode? Ok, is that an easy fix if that is indeed the case?

• #9

Aye it ordinarily is an easy fix if none of the other components were damaged

• #10

Yes it normally is an easy prepare if none of the other components were damaged

Cheers for your input, hopefully that's all it is.

• #11

It should have been OK with 18v, is it possible the adapter was the wrong polarity?

Anyway, yes, the protection diode is fairly piece of cake to supervene upon and I know Alchemy has done it on Klon KTRs and other pedals.

18V should have been fine, information technology's simply a TS derivative. Information technology's likely simply a switch.

Before you lot mail the pedal anywhere, take the dorsum plate off. If it'due south a LP build Zendrive, the switch will be mounted direct to the PCB. That should be fine to send to a repair shop. If the switch is dissever from the PCB, there'south a solid chance there's good on the excursion board. If that'south the example, it may not exist worth sending to anyone or getting repaired (depending on what actually failed).

How much did you pay for the pedal? If it'due south one of the LP built ones, you'll likely be meliorate off buying another. The bench fee most places charge to exercise anything is probably half of what you paid.

18V should have been fine, it's but a TS derivative. It's likely merely a switch.

Before yous mail the pedal anywhere, have the back plate off. If information technology'south a LP build Zendrive, the switch volition exist mounted straight to the PCB. That should exist fine to send to a repair shop. If the switch is separate from the PCB, there's a solid risk there's good on the excursion board. If that'due south the case, it may not be worth sending to anyone or getting repaired (depending on what actually failed).

How much did y'all pay for the pedal? If information technology's ane of the LP congenital ones, you lot'll likely exist meliorate off buying another. The bench fee virtually places charge to do anything is probably one-half of what you paid.

I accept the ruby-red version Zendrive, I know this was a limited run made for guitar middle which has slightly more gain than the standard models. I bought it used a few years back for well-nigh $85 if I remember correctly. Then I'yard unsure what the difference is regarding the circuitry configuration , any further thoughts Calfzilla?

• #14

One more crash-land with updated info on the model I have, so I can become a amend idea if information technology's salvageable in response to what calzilla posted. And then it's the red version zendrive, thanks for any further input.
