Overdrives are often talked about, and I must admit for a long time I was somewhat ignorant. Only in the last year or so I learned how they can be used to boost an amp, rather than for their own overdrive/distortion.
When I pair this with an old Marshal, it makes the amp sound so tight and cutting, the kind of tone I always wanted but for years struggled to get!
These are so cheap, and the impact they have, I believe now everyone should have one! An overdrive can save an amp that sounds too dull or doesn't have enough bite. Set drive to 0 and level to max, and it pushes your amp into a nice and tight, cutting saturated tone.
Highly recommend this!
