Rifftone is a small American guitar effects brand whose products are distributed through Earth City Sound Co., a Texas-based seller of affordable pedals, power supplies, and accessories. The line is best known for utilitarian gear aimed at working players on a budget, including the RT-12 Performer isolated and regulated power supply with eight outputs and selectable 9V/12V/18V switching, the more compact M-80 Mini effects power supply, and the RT-2 Mantra, a true bucket-brigade analog delay offering roughly 20–600 ms of warm, tape-style echo with true-bypass switching.

The brand maintains a minimal web presence at rifftonefx.com and reaches most customers through Reverb, eBay, and Amazon listings rather than traditional dealer networks. Coverage in player forums and blogs tends to frame Rifftone as a value-oriented option in the BBD analog delay and pedalboard power supply categories rather than a boutique builder.

Rifftone has 2 products cataloged on Equipboard, including Effects Pedal Accessories.
