Ibanez ES-2...Modulation mod?

Anyone? I'm aware this is a long shot, and even if someone out there managed to come up with a schematic for somekind of rate/speed control for the modulation, there's a good chance I won't have teh skillz to pull this off myself anyway :(

It's just that right now the modulation is completely useless to me. I don't normally care much for subtlety, but in this case it'd be great if I could somehow make that wobbly freakiness more musical/dreamy/psychedelic, and less over the top and annoying.

Either way it's still a killer delay for the money impo. The ability to play on top of a bed of nicely controllable mooshy ambient oscillation isn't something I dreamed to find in an affordable analog delay :)

It looks like it's SMD, so unless you've got skills or cash it's gonna be tough. But, it's got trim pots -

I'd open'r up, mark the stock settings with a pencil, and see what happens... If you're lucky one of the trims will be for modulation and you'll be able to dial in sumthin' you like.

Thanks!

Hadn't open'd it yet, had no idea there were a bunch of trim pots in there. I must have missed that in the manual. Thanks for the tip, definately worth a shot.

Be really careful with the trims and DEFINITELY make sure to mark the original places if you don't know which does what

Yeah, I'd guess they're delay chip calibrators and have nothing to do with the modulation.

On analog delays there are often on-the-board trimmers to optimize normal performance, like to avoid generally unpleasant noise levels and odd distortions. These things generally aren't a matter of tone seeking so much as final quality assurance adjustment. It's kind of a finicky balancing act of compromises to try to get good bandwidth, low noise, and maximize delay time. Usually there's kind of a narrow sweet spot of high fidelity-ish performance. While we tend to like some of the non-ideal zones for tone chasing, best to mark the original adjustments and go slow.
