Bass amplifiers take much more abuse than guitar amplifiers.  To create the same bass tune at the same volume as a guitar riff takes much more power to move a larger speaker.  Many bass amplifiers we see for repair have shaken themselves to pieces.  Often it starts with the transformer, then the PCB wires shear off, we had a spate of one brand where the transformers started rattling around and all caught fire!  We'll repair all kinds of solid state and valve bass amplifiers from our Harlow based workshop.  

Generally our services only include repair however we have carried out a small amount of modifications.  We will consider all modifications however if you appear with a forum related modification we think is unacceptable or will not deliver what you expect please do not be offended if we decline to modify.
