Amplifier Discussion / NO soldering wireless guitar amp project.
« on: November 11, 2017, 02:28:16 PM »
Probably been done before but...
Headphone amp + fm mps transmitter +  any FM Radio = wireless guitar amp

Works well with my Technics HiFi. Using a better headphone amp (eg Vox.ones) and transmitter might improve matters. Need to keep amp volume low to stop the transmitter clipping. Little chance of hurting the receiver as the FM signal is weak enough. Plus the neighbours can hear  my killer riffs if they tune in to
106.7 FM

Any suggestions for preamp design?

Mackayprod, thats cool. Are you using the Velleman kit, or just the TDA2003 chip which is at the heart of it? I got kit from Maplins (the UK/Ireland equivalent of Radio Shack)

Been playing with it again and decided I like it (or am too lazy to modify). basically I play it quiet or else flat out (wakes the family if not the neighbours) and theres no in-between. One mod I heard of is to use a smaller resistor going in to the inverting input. this increases negative feedback thus reducing the gain. I based the enclosure design on the Pignose (imitation, flattery and all that) though its a bit smaller. I put a bit of effort to fit a DC input jack and also a headphone out jack, so I can always change the guts while keeping the enclosure (of which I'm quite proud). Mainly used with my homemade Lap Steel and a Hofner Shorty guitar. Actually sounds great as a Harmonica amp too.


Letting the battery run down gives more distortion anyway (sometimes in a good way...) as Brian May did with his Deacy amp. You can now buy a Deacy replica including a variable power supply to simulate a dying battery but wheres the fun in that?

Think iIl just accept that i can have quiet and clean or loud and dirty.  For quiet and dirty i can use my overdrive pedal. Will be back for more ideas on my next build-possibly something tiny with a 2" speaker just for fun.

Thanks for that. It can take up to 18 v so will look for a new supply ti deliver that. Or 12 AA batteries. Would a 4 ohm speaker help?
