If you take a classic JTM45/Bassman circuit, bridge the inputs internally, and broaden the frequency response, this is what you get. Big low end from a custom Heyboer output transformer, plenty of upper mid bight, and reverb that creates ambience. Cielo is a versatile amplifier that works well with any guitar or speaker configuration. Now with power scaling, you can dial in just the right volume without sacrificing tone.

Cielo head price is $1350 + $25 shipping to the continental US.
