Re: Wiring Woes.

Will do that next time I take the control cavity cover off and trace through the spaghetti.
The main cause of the confusion was the lack of a schematic for the eq unit. The epiphany came when I realised I needed to be switching the output from the eq and not trying to interrupt the input.

Re: Wiring Woes.

All sorted eventually. Both LED's have a current limiting resistor in series as they were way brighter than necessary anyway, so battery drain isn't too much of an issue.
Capacitors sort switch clunk.

Re: First Bass Builds

The switch nearest the jack socket cuts all output, basically battery saving.
The second switch bypasses the graphic equaliser /pre-amp and takes the signal straight from the blend pot and volume to the amp.
Each switch has an indicator LED.

Re: First Bass Builds

Was aiming for a warm tone, which they deliver in spades, but may need to calm them a bit with a series resistor to prevent feedback when in the same postcode as the amplifier!!

First Bass Builds

Having seen some of the many six stringers I have built over the last few years, the bass player in our (embryonic!) band asked if I would build a bass. The design influences are obvious so I accept no credit for styling. I decided to make a fretless at the same time. Everything is hand made by myse...

Re: Wiring Woes.

Have got power switch working and bypass almost there, it seems to be the simple bit i.e. the LED'S, that are giving me the headache.

Re: Wiring Woes.

The third wire to the jack socket is for cutting power when bass is not plugged in. The blend pot and volume pot are part of the eq unit, but ideally I would like to retain these functions and just bypass the three band pots. The thinking behind the dpdt switches was to use one side for function and...

Wiring Woes.

I am close to completing two five string basses, one fretted, one fretless. Both have a three band graphic with standard 9v battery supply. There is a graphic on/bypass switch and a power on/off switch. Each switch is dpdt and each has an indicator LED above it. Have been racking my brain to figure ...

Re: Anybody paint their pickguards?

I have used clear Lexan for Strat pickguards, 'backpainting' artwork including Pink Floyd's 'The Wall' and 'Dark Side Of The Moon' on the reverse side. This is protected by a full foil screen covering, glued on with spray-mount adhesive. Plastic sheet available from model/hobby shops is just the rig...

Re: How to reverse a motor?

I assume this is an induction motor i.e. brushless? If it has two removable endcaps and they are the same dimensions, you can simply flip the rotor to reverse it. NOTE WELL : any pulleys etc that are mounted on a screw thread are right or left hand threaded so they are self tightening in normal dire...

Battery powered amp.

This may be in the archive, but I am currently browsing on my 'phone. Is it okay to wire in a suitable voltage battery supply at the amp's rectifier output for street performance use ? The diodes in the circuit should protect the other electronics/electrics before the rectifier. I think ! Anyone had...

Absolutely stunning ! How this guy achieves photo-realism on wood is just amazing. A true artist.
