Lectric Dandy Horse - dark sound

[magicman]

Greetings, I have a Lectric Dandy Horse I have been trying to tune and I get significant treble roll off when the effect is on. The chorus flanger and echo sounds are still great, but it sounds like someone threw a blanket over my amp when it's on. I have a 2005 reissue Polychorus (different circuit-I know) and it sounds signifigantly brighter of a chorus sound. I just wanted to verify if this is how the original unit is supposed to sound.

Thanks everyone in advance.

It's a more neutral circuit- shouldn't be too bright or dark. It's possible you put a higher value cap somewhere in one of the filters

Got some pics of your build?

Thanks for the reply! That's what I have read about it, that it is very neutral sounding, it really surprised me how dark it was. I was meiticulous, but there are so many caps in this thing...its possible I made a mistake, maybe got I a multiplier wrong somewhere in the filter.

That's where my brain went, I will get some photos and a sound sample up here a little later.

Input impedance in this circuit is less than 100k. That can cause some audible loss of high frequencies if you are using 'true bypass' all the way. Try to connect some pedal with an active buffer before your Dandy Horse in your signal chain and check if that helps.

Thanks! That is a good thought too, I have tested it a bunch by itself. Right now it is in the middle of my chain, which is mostly true bypass but has a Boss TU-2 towards the front.

I am familiar with the issue with my Boss CE-1 clone, which is true bypass and has a drastic roll of of treble when it is used by itself. That is also on my board, about 5 or 6 pedals after the Dandy and it does not experience the treble loss with the Boss TU-2 in front of it. Even 15 or so pedals away and the buffer still works.

I will give it a shot though! Maybe it just doesn't like being in this spot in the chain or by itself...

Okay, then that is not what is causing an issue in this case.

I tried my Dandy Horse build with various instruments, like synthetizers, guitars, bass, and never noticed any treble loss, even by itself.

I'll play around with some placement, I'm not totally ruling out that it isn't influencing it as I did opt for the true bypass scheme. Thanks for the idea!

Thanks for the feedback, I appreciate it. It is very helpful to hear how other people's units sound. There is a noticeable treble roll of on mine with any instrument. I've mostly been playing it with guitar.

it's a very long shot but i'd suggest to carefully check all capacitors values, maybe you misread a value on a part somewhere.

Could easily also be a bad soldering joint that looks perfect.

In that case, i guess you'll need to audioprobe the signal path and see where the treble loss happens.

Thanks for the reply. I just check all of my cap values, they are all correct. Busting out the audio probe next.
