The Diva Drive from Danish effects specialists T-Rex contains the legendary JRC4558 op-amp - as found in vintage TS pedals for juicy, mid-boosted gain.
The Diva Drive boasts a mix control for blending the overdriven signal with your clean tone, while a three-way low-end boost control tailors the bass response to your guitar.
The mix is handy for retaining clarity with extended chords, while the low-end switch is an easy win for filling in the gaps in your sound.
