Advances in in-ear monitor technology and the pursuant lower stage volumes led to the need for low-powered amplification solution for guitar players that still sounded as full and rich as larger tube amps.
The amp was first shown to the public at the NAMM Show in 2004; Boul left his employer to devote his time to 65amps full-time in 2007.
He started with an 18 Watt Marshall and a Vintage VOX AC15 as his inspirations, and after much experimentation, he evolved the circuits of his amps to be more tonally versatile.
[1] 65amps are handcrafted in North Hollywood, CA, using high-quality components, including optimized transformers from Mercury Magnetics.
The initial product offering, dubbed the "London,"[2] made its official debut at the 2005 Winter NAMM show.
