Original Message 1/8 06-Jun-00 @ 07:18 AM - moding tr-909's ride
Hello. I have two tr-909's and both sound totally different as all 909's do. But I'm looking to get a extrememly loud ride cymbal out of one of them. Does anyone know how I can modify one of them to have a louder output? If I cant do this, I'm just going to keep selling one off, then re-buying another one until I find one with a crazy ride cymbal. Any info will help, or anyone looking for a really good condition 909 for trade with one with a really loud ride may be considered? Who knows?
Anyway, hope someone can help!
ian

Hello Ian,
Do you simply want to increase the output level of the ride cymbal circuit? To do this, replace R446 for a resistor of a lower value. This is the input resistor for the final opamp in the ride circuit. Or, add a resistor in series with VR26 to increase the opamp feedback resistance. Either way will work.
This will work but without having tried this mod, I cannot say offhand if you'll get significant distortion / change in the opamp's freq. response etc. Give it a try.
If you cannot be arsed to remove the entire pcb, you could simply solder a resistor in parallel with R446 on the solder side of the board to get a lower resistance.

Jeeez!!! Sorry about that... I just wanted to make a point ;-) I think something went slightly fecked up there ;-)
Trev (feels rather stupid)
