The Ultimate GA15 Mod Kit – Classic Version

 29,95 54,95

May 10th, 2020 – Check out the brand new Legendary 18 Watt GA15 mod kit” and turn your GA15 into a GA18, after a famous British example!

“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 the little Harley Benton® GA15 guitar amplifier, we’ve gone to great lengths to improve its mediocre design from the ground up. The mods in this kit (click here for the full story) convert the GA15 from a dull 50% solid-state amp, with 2 TL072 ICs in the preamp, into a pure tube amp, with a warm sound and great playing dynamics. Hum is greatly reduced. With a suitable extension speaker your Harley Benton® easily gets enough power to play in a rock band!
This is a carefully selected set of electronic parts. It comes with an elaborate 27-page instruction manual (scroll further down). A full-colour print-out of the manual, convenient on the workbench, is optional. Other options are high quality tone capacitors (Mallory 150s and Silver Mica type) and/or a presence mod.
