    I just received a DS-1 i bought on ebay for "pocket change" It was one of those "Bad Monkey" moments. So cheap that if i won it i could always get it moded or whatever...
    By looking at it i noticed that it needs an ACA adaptor!? hmmm so i looked up the serial number. 1989! Black Taiwan label. Toshiba TA7136AP opamp ! wondering what it'l sound like! And if i should get it modded?

    Check with AnalogMan on the mods, but see if you like it first. He is pretty straight when it comes to what does not need mods. I think he said the Japanese ones (older than yours) may be good and not need modding.

    He may even have the aca adapter too!

    Get it dated and valued, BEFORE you think about modding it. it could be worth a packet. And adding to it by modding will decrease this price.

    I need a little education here.

    The older ones from the 80's are different than the ones they have out now? Geee the one I have I guess I should have never painted and put stickers on it. :jo

    hmmm that's strange! I can't beleive the sound i got out of this thing! At one point i was really pissed to see how good it sounded! I paid $21.00 For c... sake! It is an old circuit old chip! I assume that's why it sounds good. Level, dimmed, distorion at 2:00 If I set the tone too high it does sound like ass. So i have to bring the tone back to 9:00 and compensate with the amp settings....i was floored.

    Actually, most DS-1s sound alright with the tone knob at 9:00. The problem with this, of course, is that you're losing some high frequencies, so it's a tricky balance
