Steve: No offense taken! You know, at my job I've been looking at the same antenna pattern for the past year trying to increase its efficiency, decreasing its transmission loss, and coordinating device fabrication that I often lose sight of fundamental physics, the bigger picture, and common sense. ...

Oh dear. :eek You're right, Steve. Major oversight on my part. I guess you wouldn't believe me (or would find it scary ) if I told you that I research and develop radiotelemetry/RF-power systems and advanced conductor materials all the live long day. (And yet RC circuits still puzzle me.) Crazy worl...

Steve: By stability, do you mean that it helps tame oscillations? Would I be able to go more broadband and obtain flatter response in the low DR by short circuiting the capacitor and smaller resistor (R91)? I realize this is at my own risk. Since I think the stock sounds of the VM in high range are ...

Dean (or Steve, if you're the type that like's to divulge your expertise): Do you know what c80, R58, and R91 do? C80 is a 1 nF cap, R91 is a 15k resistor, and R58 is a 30k resistor. They're coming off the cathode of V4 after a 10k voltage divider. Does this look like a low-pass bunched together or ...

Thanks, Dean. (Assuming that I have my parts correct) I was thinking that maybe C8 and R11 would be the low-pass, but then I realized that they are tied to V2, which shouldn't affect the low range. The 68k R2 appears to be the same resistor found on old Bassmans (which should be the same as JTMs). S...

This question might be best answered by SteveD, but if anyone else knows... Is there low-pass filtering happening in the VM preamp after the "Body" control? The amp is somewhat pedal friendly, but I can't help but hear some attenuation in the high end when the amp is set to low dynamic range and the...

Thanks, Steve.

What do you think about the reverb problem?

Hi, Vintage Modern forum, First post here... with some perplexing questions: Is anyone else on this board experiencing volume dropout when engaging their FX loop (cable plugged in or not)? The volume loss is more apparent for me on the low dynamic range mode and the loss of gain is more apparent in ...
