I just bought a Bugera V5 for a home practice (baby asleep in the next room) amp.
I love everything about it except the high end... or lack of.
how would I go abotu finding the right way to sneek more high end out of it. Would any of the Epi Valve Jr mods apply?

Theodog Maybe send an E to Wampler with that question or try Arron Nelson's forum. Or Indyguitarist forum. Would a treble booster work???????

I've not been inside one of these, nor have I seen a schematic, so take this for what it's worth...

On most single tone knob amps like that, you can coax out a little more treble by changing out a single capacitor. Thsi mod is frequently called a "bright cap" mod. I have no idea if the V5 and Epi are close in construction or not. In other older small point-to-point amps, that particular cap would be soldered directly onto the back of the tone pot, but being (probably) printed circuit board it could be anywhere depending on the best trace layout. Care to post up a gut picture?

Another way to find it would be to grab a multimeter and start looking for continuity between the back of the tone pot and one leg of a capacitor. Back in the day, it'd be a small tan non-polarity conscious disc
capacitor, but in this era of surface mount stuff it may well just be a small black rectangle.

I'll see if I can find any gut pics on the net. Schematics are going to be hard to find on an amp this new.

I'll try to get arounf to a pic for you Hz. A treble booster woudl work, but goes against the stripped down concept of a Guitar -> amp setup. I have already blown that out by using my 3rd gen modded Dynacomp with much succes int he Bugera, but that alone is also ripping out some high end shimmer.
maybe a Tele is the answer.

Maybe putting a tweeter in your guitar cab is the answer. Certainly cheaper than a new guitar (pick one of the piezo versions) You can probably just set it on top of the amp for a while .

I'm sure I could research enough to just find a different 8" drop in replacement speaker... maybe a weber or something. I am thinking this bright cap mod might be an answer.
If my kids would tak ea nap while the turkey is in the oven, I might post some PCB pics so we can work on it together and help all the Bugera owners love their V5's more.

the components seem pretty easy to swap out http://i127.photobucket.com/albums/p130/darko240sx/DSC_0083.jpg

I think I could use a multimeter to test polarity. How woudl I know what to value to swap? Or where I should start hunting. I guess I could take the chassis further apart and trace the PCB, but ... you know... kids... wife....
that isn't really a picture I took, I found it on alt.guitar.amps in Yahoo!
