The Ultimate GA15 Mod Kit

29.9554.95

“I had one of Swedens best modders help me as it was quite some job for an unskilled like me. The amp sounds Cosmicly nice. It really opened up after the mod. Mod 7 was newer made” – M.R.

To bring out the full potential of your little Harley Benton GA15 guitar amplifier, we’ve gone to great lengths to improve its mediocre design from the ground up. These mods (described in more detail here) convert the little Harley from a dull 50% solid-state amp into a pure tube amp with a full, warm sound and great playing dynamics. Hum is greatly reduced. With a suitable extension speaker it gets enough power to play in a rock band!
The mod kit itself is comprised of a carefully selected set of electronic parts for implementing the mods. It also comes with a 27-page full-colour instruction manual, but to reduce costs, you might want to choose to just consult the online version, rather than ordering a printout.

Description

This mod kit is comprised of a carefully selected set of electronic parts for implementing the “Ultimate Harley Benton GA15 Mod”, developed by Cosmic Ampworks. The printed 27-page full-colour manual is optional (view it online here).

Despite its charming looks, the little GA15 in its stock condition just doesn’t bring out the best in a guitar. But, the good news is that it already contains all the basic ingredients that make a great tube amp!
To bring out the full potential of the GA15, we’ve developed a number of drastic modifications. These mods (described in more detail here) convert the little Harley from a 50% solid-state amp into a pure tube amp with a full, warm sound. They also reduce hum. With a suitable extension speaker (not included) the GA15 gets enough power (a bit more than 18 Watt) to play in a rock band with a loud drummer.
In the extensive step-by-step manual (full-color printout is optional), the mods are arranged in order of increasing complexity so that there is some room for learning along the way… The mods may be quite challenging to perform if you have no previous experience at all with electronics! A list of the required parts is provided on page 6 of the manual. Included tone capacitors are a mix of Mallory 150s and Silver Mica types (optional) or standard ceramic caps. All included potmeters are Alpha brand. A presence mod, comprised of additional presence and negative feedback control on the back of the amp, is optional too.
