Full Description

Real amp feel in a compact pedal

The 63 Diamond’s multi-stage analog circuit is voiced to mimic the touch response of a real tube amp. Your playing dynamics shape the sound naturally, from soft picking to aggressive strumming. Run it into a clean amp for added texture or use it straight into a cab sim or interface for a full amp-style experience. The response is lively and expressive, giving you plenty of control at your fingertips.

Boost function for added punch

A dedicated boost switch gives your tone an extra kick when you need it. Use it to saturate your signal for solos or tighten your tone for riffing. The boost is tuned to enhance clarity and presence, helping your guitar cut through without becoming harsh or overpowering.

EQ shaping with classic voicing

The tone section is inspired by the EQ curve of classic Black Panel amps. It gives you the ability to dial in familiar clean and driven sounds quickly. Each control is responsive without being overbearing, so your core tone stays intact while still offering useful flexibility for different styles and setups.

Built-in preamp simulation

A switch on the back activates preamp emulation, ideal for recording direct or playing through a modeler or PA system. It recreates the feel and response of a traditional amp front-end, giving you a consistent tone when you’re not using a real amp. Perfect for silent stages, home studios or compact rigs.
