Here are a couple of Marshall JCM900s guitar amplifiers we’ve had in our workshop for repair in the last few weeks. The one on the bottom simply need new output jack. Unfortunately the one on the top needed a new mains transformer and power valves, a significantly more expensive repair. These are original early 90’s amps, and I…
Here’s some photos from a pair of Orange Crush guitar amps I’ve had in for repair: a 15R and a 30R. Both had a very loud hum when the amp was at idle. In a solid state amp this is almost always due to poor power supply filtering. and further inspection showed that this was caused…
Here’s a piece of history. This is the actual Barnes and Mullins Fuzz used by Edwyn Collins to record his classic track Girl Like You. The pedal was in the work shop for repair; nothing seriously wrong with, a broken solder joint on the PCB.
Peavey have earned a reputation for making well-engineered amps at reasonable prices, so I was not expecting any major issues when I took in a ValveKing 100 for repair. The symptoms where that the amp was not powering up: neither the indicator light, nor the valve heaters where illuminated. This fault is usually due to…
There are now a ton of different colours you can get Tolex in, so we thought we would experiment with some different combinations. Here we have silver/ black and purple/ ivory.
Here’s Fender Hot Rod Deluxe that came into our workshop in need of new filter caps. Whilst you would expect the filter caps in, say, a 40 year old Fender Twin Reverb to need changing, it’s surprising that the caps in a 10 year-old Hot Rod Deluxe should have expired; however from my own experiences,…
Check out the new Little Barrie album “Shadow”. Barrie used a JPF Regent combo and a Fender Blonde Tolex Bassman for all the guitars on the album. You can see (and hear!!) Barrie demoing the combo on our Youtube channel.
We were asked to make a valve pre-amp for a customer who wanted a simple clean Fender-style pre-amp, mainly for playing jazz. Here are some of the parts before the build. The PCB is a charge pump circuit from Tube Town that boosts the incoming voltage (12VDC in this case) to a user-adjustable 90-220 VDC….
Here are 3 Lovetone pedals that we have recently repaired. These are rare and valuable pedals. The Dopplerganger is a phase/ vibrato pedal with 2 low frequency oscillators and is a particular favourite of mine. The Meatball is an envelope filter, and the Ring Stinger is a ring modulator (which I would have to say…
Here a picture of a custom footswitch we made for a Fender Vibroking. The problem with the amp’s stock footswitch is that there are no LEDs on it to indicate which functions have been activated, so we built a footswitch with LED indicators for each feature. The LEDs can be powered either from a battery…
