Cobblestone
Kartakou Cobblestone Power Amplifier
During your band rehearsals, you may notice that your guitar rig sounds different when plugged into various amplifier stacks. Even the most expensive heads seem to modify your tone, which may ruin the creative process and drive away your muse far beyond the horizon.
I wanted to solve this problem, so I spent months designing a portable amp that would have no disadvantages.
The result is Cobblestone - a universal guitar power amplifier delivering 45 watts in a small, pedal-sized housing. Cobblestone works remarkably well with any pedalboard, effects processor, or preamp, and can drive any load starting from 4 Ohms which other popular portable amps can’t.
The amp produces 45 watts of pure, clean power, making it perfect for home practice, rehearsal, or small gigs. It carefully amplifies your tone, preserving even the subtlest details without altering your sound.
Cobblestone sounds great at both low and high volumes, delivering a solid punch no matter how loud you play.
