Hot Mods
Fargen Hot Mods [Guitar Amp Mods]
The Fargen Hot Mods line was developed to help players turn their standard sounding vintage and production amps into world class tone machines. Once you have a Fargen Hot Mod installed, your vintage or modern production tube amplifier will be worthy of stepping toe to toe with any boutique tube amplifier on the market.
Fargen Hot Mods offer our recipes of components and modifications developed over 16 years of repairing, restoring and modifying guitar amplifiers. “I have seen the best of the best come through our shop over the last 15 years and I have documented why certain amps were much better sounding than others” It all comes down to parts drift ,rare factory circuit variations and some dumb luck. Certain components drift in a way that the designer could never have predicted… thus creating a unique and rare tonal opportunity.
Fargen Hot Mods replace all the inferior caps and resistors used by most amp companies. Your amplifier will be upgraded with world class components that are made especially for the Fargen Custom Shop. The combination of new custom components, new circuit revisions and new Custom Mercury Magnetics output transformer/choke enhances what any tube guitar amp has to offer in tone, note balance and sustain.
We’ve worked with Mercury Magnetics for over 8 years co-developing custom audio transformers for the Fargen tube amp product line as well as upgrades for famous artist amps. Here is your chance to access that same attention to detail with direct replacement transformers for your Fender, Vox & Marshall spec’d out for optimum tone and performance by Benjamin Fargen per the Fargen Custom Shop requirements for tone. Unlock the tonal potential of your Fender, Vox or Marshall amplifier with a Fargen Hot Mods transformer upgrade today!
