How many instruments have you built so far?

What do you find most interesting about cigar box guitars? (If you do not enter at least one meaningful sentence, your membership may be rejected as a spam/bot fake account).

The pure raw gritty sound that only comes from a cigar box guitar. I love how easy to play they are - i prefer playing my cigar box guitar than my very expensive acoustic guitar. I love how forgiving they are when you make a mistake. I just love playing and building them so much - they have given me a new found passion that I lost a long time ago once I had finished playing in bands.

"Oh wow thankyou so much brianQ that will help immensely - I'm sorry I didn't make myself very clear from the start. My client wanted all these options loaded into the guitar and he purchased and supplied the preamp with rod piezo, deltabucker…"

"Hi again Mal, the y cord I used I made up myself. Taff"

BrianQ. replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"I was confused when you mentioned the preamp because you didn't mention it was for a piezo, I thought you were using it for the humbucker? Usually running a capacitor across the output wires of the piezo will stop the feedback? Your problem is that…"

Malcolm Mannagh replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"Thankyou BrianQ for that - i think I know what you are explaining. Would it work like Taff suggested and wire them separately and have two output jacks and use the jack that came with the preamp and a standard jack for the humbucker and psycho knob.…"

"Wow what a cool guitar Taff - if it can't be done i may have to go that way also.
The only worry I have is whether we can get a lead with the Y junction here in NZ or if I have to order overseas. Thankyou Taff"

BrianQ. replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"Mal, you didn't state which model Fishman preamp you're using? It could be that the one you're using is made for piezos, did it come with a piezo? "

BrianQ. replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"Yes, a low z would be the only reason to use a preamp on a magnetic pup, but most will just plug into a DI box to get a high z output?"

BrianQ. replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"I would go with just the psycho knob, the screeching you are hearing is feedback, the two circuits are slamming boosted signal at each other, creating oscillation, a common sign of "too much"? "

Taffy Evans replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"Hi Mal, I found photos of the guitar with two pickups and two Jacks.

Cheers taff"

Taffy Evans replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"Hi Mal, yes the system worked well in two of the solid-body guitars I used it in. Sorry, I can't post a video. The magnetic pickup was used to just add a more robust bottom end to the thinner-sounding piezo pickup. Or of course, one could have full…"

Malcolm Mannagh replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"Thankyou for that taff yes I'm the same. I was a cabinetmaker and these electronics are new to me I can generally figure it out but this one has me stumped. I may have to wire to separate circuits entirely, I don't really want to, but I may be…"

Malcolm Mannagh replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"Thanks BrianQ for your advise yes this was at the request of the client he purchased the preamp, humbucker, psycho knob and the Anzac biscuit tin and I supplied the neck material and other small parts and are building a 3 string for him with all…"

Taffy Evans replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"Hi Mal, I thought I would leave others to give a more detailed answer as I did not know what a Psycho knob was. I have made guitars with the setup you are asking about. I do not have a wiring diagram. What I did was to wire two systems wired as they…"

BrianQ. replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"The stereo jack is there to act as an on/off switch for the battery, so I would leave it as is? Also, the psycho knob is a preamp too, actually it's a preamp & boost, so I don't think you need both, especially with a humbucker? The fishman preamp is…"

Malcolm Mannagh replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"Thankyou Taff i really appreciate the advise - I will search guitar electronic you suggested. If the white wire of the jack that was attached to the preamp already is to turn off the battery of the preamp, then where would I attach the white wire in…"

Taffy Evans replied to Malcolm Mannagh's discussion Psycho knob preamp wiring dilemma

"Hi, search Guitar Electronics I find a good site listed there, many different combinations shown, was using it last night. I think you will find that if that premamp is active the stereo jack is for switching the battery off when guitar unplugged.…"
