Grandville Head
Roughly 3 years ago we floated the idea to Rhett about an amp collaboration. After all, Rhett's name is synonymous with great playing and terrific tone. He said he would think about it. It was only when Rhett played an early 50's Gibson amp during a session that he reached out to get the ball rolling.
That amp was the inspiration and starting point for the prototype amp. After 9 months of work we created what would eventually become a completely unique amp. An amp that delivered the quality of tone, features and aesthetic that Rhett demanded.
After some time with the amps, Rhett asked to modify the circuit. He wanted to add a reverb circuit and he wanted the amp to be able to break up. The new Grandville still has warm cleans and lush tremolo like before now with a custom reverb circuit and more gain on tap.
(This amp was developed in conjunction with my friend Steve Snyder at Inspiring Devices.)
With a simple set of interactive treble and bass controls with a single volume knob players are able to sculpt a wide array of tones. The Grandville using all octal preamp tubes provides a lush, warm yet unique tone.
Using premium components each Grandville is hand made outside of Asheville, NC. Whether it's being used at bedroom volumes or on stage the Grandville is more than capable of delivering great tone. Guitarists that use effect pedals to achieve an overdriven tone will be amazed at how the Grandville brings the best out from their pedals. During the development of the amp we tried a number of different speakers and in the end found the combination of the 10” Jensen Jet Tornado and 12” WGS G12-CS to be the perfect pair. (The 10 / 12 Wave cabinet is available for purchase in the customize section.)
