    Maarten,

    Thanks for the reply!

    I've got a couple of other questions, if you don't mind.

    I would be attempting this on a pro vla 2, and I'm pretty sure the part numbers on the board wont match up exactly. Is there an easy way to identify the target resistors based on their placement in the circuit?

    Also, how did you mount your pots on the outside of the unit?

    Sorry, I'm very new to modding and electronics stuff, so I know next to nothing... Done some component swaps and troubleshooting in mics and preamps, but can't really parse out a circuit by looking at it and I don't know how to go about modifying a faceplate in a non-catastrophic way

    Hi,

    I've installed the pot on both channels and the range is subtle. So stereo matching is very easy if you would implement it on both channels. If you only implement it on one channel, then that's cool too, if you turn it all the way down it will function just like the stock channel!

    Good luck

    Hi Tubefreak

    While perusing some threads about the ART pro vla, I came across your mod thread where you swapped out the opamps and did some other things. I'm interested in trying the variable tube overdrive mod you made by putting in a pot to control the negative feedback, but I'm not completely sure whether it would be a good idea to attempt it or not. I'm concerned that if I put the pot on one channel (which is my current plan, who needs a stereo distortion box?) it may become impossible to get good stereo matching of the sounds and ruin the pro vla for critical stereo applications.

    What are your thoughts on this?

    Thanks, and thanks very much for posting your modding experience however many years ago that was
