Leo '64 Amp

Heptode Leo '64

The Leo '64 amp head uses an innovative technology developed by Heptode that simulates perfectly a tube amp.

It offers a unique solution that provides sound quality, awesome looking and ease of use.

The tube sound ... without the tube problems!

The Leo '64 offers the same sound, dynamic response and harmonic content as the revered Fender* Blonde and Blackface amps that inspired it.

The Leo '64 weighs just 3 kg (6.6 lbs)  and is housed in a beautiful handmade mahogany and maple cabinet.

If you do a lot of gigs, size, weight, volume and reliability are serious issues to be reckoned with.

The Leo ’64 addresses these concerns with it’s small size, light weight, adjustable output power and rock solid reliability to make the Leo '64 the ultimate guitar amp at home, at rehearsals, in the studio and on the concert stage.

" I've been dreaming for years about an amp like the Heptode Leo '64. It combines two tonal characteristics that are often contradictory: pristine cleans and warm overtones. The Leo ‘64 perfectly reproduces and amplifies the electric guitar source with or without pedals or a complex effects rack like the AxeFX.
A pure balance between water and fire, inside an incredibly light and super cool looking cabinet!"

"When I first saw the Heptode Leo '64 amp head I was a bit skeptical. But after playing thru it for a few moments, I had to face the facts: its small size (not unlike a portable radio set) and light weight were concealing an exquisite sound with warm overtones and a great dynamic response that most certainly would have made Leo proud. On stage or in the studio, with clean or cranked sounds (I use a BB Xotic Preamp), the result was beyond expectations. I anticipate that the Leo '64 will enjoy much deserved success."
