Im having problems after completing the wiring for the boost. my volume pot is really sensitive and with my amp volume barely on (< 9:00) and my guitar volume on 10 it is mildly overdriving the amp. my amp is a epi Vjr. this is with no boost on. i have it wired the same way that it shows on the diagram except i had to move the TBX to the back pot and the boost in the middle. the boost works exactly the way it should. my pickups are Lace Hot Golds. anybody who has installed this kit i would appreciate your help. was it like this for you??? could i have put the 250k pot in the volume and the 50k for the boost pot??? but im damn sure i didn't switch them pots. could it be my pups?? should i put a 250k in the vol pot??it just seems really loud as compared to before and the pickups are around the same output.i know the boost is always on but it is not always adding drive. i have listened to every demo available and i never get their clean tone and there drive just sounds creamy and mine sounds harsh. could it be my amp is too small (Epi valve jr 5 watt combo).
thanks for your help.

Sight unseen and based on what I can deduce from your paragraph, the 250K pot should be the volume pot and the 50K should be the boost pot. If they were reversed, you'll get the kind of response you are describing.

OK, I just looked at the schematic (which I should have done in the first place). I see where the boost is placed in the guitar's circuit and that the volume pot should in fact be, 50K.

Due to you getting that whacky volume pot taper and minimal overdrive could very well be that you reversed the pots. Also too, something like a ground could have been left off (never trust the foil).

Is the circuit board well wrapped up? The 50k pot definately goes on the volume control. I had a lot of harshness on mine too not to the levels you described. The vintage noiseless i use are lowered all the way to the scratchplate. The circuit seems to be more a clean volume boost with a tonal change than a drive boost. I studied a few clap vid's and found that he tends to play with the boost on full and plays the volume control.

On the outside chance.
You didnt put the tbx to the bottom hole and just follow the schematic for a normal instalation did you? i did that first time round. :oops: . Not a nice aural experience.

i put the tbx in the bottom hole but i didn't wire it the way you would if it was in the middle hole. as i said before the tbx and boost work exactly the way they should. it is the volume that is screwy. it just seems super loud and i can't get a clean tone with my guitar vol on 10 and my amp @ 9:00. what could it be??? could it be a bad pot??

The circuit does boost output noticably even when its not on. I notice your using hot golds, that may not be helping. If you can swap one out for a lower output pickup it could help decide whether its the hot pickups being boosted too much. When i put the boost on my VN's i noticed they went from too low powered to too hot. I got a partial result by wiring a resistor onto the hotwire to the jacksocket. It was just some thing i had knocking about i dont know its value.

yes bbut the original clapton strats had regular golds and the hot golds are only like .2 K hotter (5.8 as opposed to 6 k)

dunno maybe it is a bad pot then. axesrus stock em but their in the uk. does the sound calm down with the volume pot at around 6? If so its exactly the same problem that i had.
