Two more custom cables completed today . These are 8 way circular locking plugs that are 4m / 7m lengths. They are for a customer whose Line6 amplifier and control pedals I modded to replace the flimsy Cat5 interconnects whose Rj45 plugs always lose their locking tabs. Bespoke cabling is OK so long as you […]

As requested a 10 meter interconnect for the Marshall AVT 150H & related foot controller. The ends are terminated with 15 way female connectors that have two lines of pins, 1-8 & 9-15. Marshalls schematic for the AVT 150H shows pins 3,12 & 13 are not connected. This allowed the use of a screened 12 […]

So the Line6 Spider HD100 Bognor tube head issue appears to be well documented online & is therefore a common fault. The amps front end is all digital DSP & as the issue resides on the main DSP board explains why no signal reaches the tube power section. Checked all test point voltages post dual […]

Maple infills for the de-fretted Columbus bass neck. The contrasting colour of the infill to the rosewood fingerboard will give the illusion of frets.

Continuing with the ‘Music City’ badged Laney 100w tube head. Google information led me to believe that this amp was a re-badged Laney Supergroup head. Acquiring a schematic for a 1969 Supergroup 100 mk1 it does in fact look to be correct. The Supergroup schematic shows the output tubes to be EL34s as opposed to […]
