I fix 2x delay pedals

I got these two well loved pedals from @Delayman. I actually only bought the Ibanez, but Dave was extremely generous and sent me the Yamaha too!

Image

The one on the left was making a sort of bitcrusher sounding distortion with a hint of delay, and the one on the right worked, but the power and in/out jacks were very flakey, it would cut out every time you touched it.

Inside of the Ibanez

Image

Typical 80/90's delay pedal, very complex circuit!

Image

All I needed to do was to re-solder all the joints on the jacks and the power connection. The battery snap had been broken and taped up, so I fixed that too.

Image

This one has been well used!

Image

Footswitch is looking pretty rough. This was actaully the hardest thing to fix, I had to take it apart very carefully and super glue it back together. Inside it's very odd mechanism, never seen a switch like it.

Image

Dave told me he thought it had been modified to work with a normal 9 volt power supply, which sounded wrong to me. So before I even tried plugging it in, I opened it up. Definitely been modified!

Image

New wires soldered (badly) directly to board, and the case says it needs a 22 volt power supply. So I doubt very much it will power up correctly with 9 volts.

Image

At one point, it looks like it had a transformer inside. It still has an intact 250 volt fuse for mains power. Interesting.

Image

80's analog goodness. And rust from spilled beer.

Image

Sexy MN3005 chip for approx 300ms of BBD delay awesomesauce.

Image

I figured that I could probably power this up with the 24volt power supply from my Deluxe Memory Man. But a quick check with a multimeter confirms that this pedal is centre negative and also the plug is 2.1mm, unlike the Memory Man which has a 2.5mm connector.

Image

Luckily I have this thing, a Powerall Charge pump. It boosts a normal Boss type power supply up to 12, 18, or 24 volts. It powered the Yamaha up perfectly. I also had to resolder the input and output connectors as they were noisy and dodgy.

Image

Two perfectly working delay pedals. The Ibanez sounds great, nice and bright and clear like those 80's/90's delay pedals like the Boss DD-2 and all the killer rack delays from that era.

The Yamaha delay is surprising, very dark tone, unlike most analog delays, it doesn't oscillate and make crazy out of control noises. It's super nice and like my Memory Man, it kinds melts away and blends in with what I play.
I could totally see myself using it as an always on slapback kind of thing, it's a seriously cool pedal.

I'm pretty likely to sell the Ibanez delay, as i have a Boss reverb/delay which has a similar sound, so PM if you're interested. 50% of the sale price will go to NZG to pay forward Daves' generosity!

Fantastic to see! I'm so happy they both worked out, and I love your pay-it-forward approach. I really liked the Ibanez delay sound, and was hoping it was something simple to fix.

I got these in a random box of weird stuff I bought off trademe a while back. I'm more likely to harm than help on the end of a soldering iron, so I'm glad you turned them into something valuable.

be sure t mark where the original position is, then tweak until you hear a high pitch scream, then tweak back till the screech disappears. you get more delay time and less fidelity. just need to find the right trim pot first

Great stuff Ben! I'm always quite envious of people with the know-how to do things like this. The extent of my knowledge begins and ends at pushing the footswitch on and off haha

that's me too! Occasionally i'll fiddle with those turny things on top - oh yeah knobs.
