Just to let you all know, there is a mod kit now available on Ebay UK
for the above amp. The gent goes under the name of Alnicomagnet and
may be familiar to some of you for his range of guitar mod kits. He
also does harp mod kits for Harley Benton, Epiphone, Peavey and Fender
Champion 600. You can check these out on Youtube by searching for
Alnicomagnet.
Below is a short quote to his auction of what the kit has to offer.
"This kit is designed to change the voicing of the amp to give a
thick, ballsy, Chicago Blues tone, suitable for Blues Harp microphones
only. After the amplifier has been modified, you may still use it for
guitar, but there will be virtually no clean sound, and it will sound
too thick especially with humbucker equipped guitars. The boost pot
and footswitch are no longer used, so I ve taken this opportunity to
use the boost footswitch jack as a line-out jack, suitable for feeding
to a larger amplifier, P.A. mixing desk etc. The line-out jack signal
comes after the output transformer so is rich in output valve as well
as preamp valve distortion. I ve also taken this opportunity to
replace the poor quality pull switch volume pot and tone pot with high
quality Alpha 24mm pots, together with a simple gentle Treble Cut
control, which is much better suited to Harp microphones to help tune
out feedback."
My kit is already on order.
Hope this helps any of you looking for mods to this excellent amp.
