The JOYO “Ocho” is an octave pedal, as the name suggests. The controls are as simple as can be: you can control the level of both octaves with the OCT1 and OCT2 knobs and the overall volume with the LEVEL knob, that’s it really. You can dive into wide and rich sound textures that make your guitar sound larger than life! And, as most of our pedals, the Ocho is also True Bypass.

R-29 Gloam

3 pedals in 1! With the Armor Buffer you get an input buffer, an output buffer and a 20db boost. When you use long cable runs, including patch cables between pedals, you will lose tone and dynamics from your signal. Even if your pedals are all true bypass. The tone and dynamics are lost due to the capacitance in the cables. The buffers are always on, they aren't' affected by the footswitch. The footswitch only affects the 20db clean boost, perfect for solo's or matching levels between different  guitars.

The IN buffer goes between your  guitar and pedals. The OUT buffer goes between your pedals and amp. By using the Armor Buffer you will not loose the tone, signal and dynamics of your sound no matter how long your cable runs.
