I have an MXR Smart Gate, and according to the manual, its maximum input and output level is +7dBV. Assuming my Marshall JVM's line level power amp serial loop is the typical +4dBu, (the manual doesn't specify the level), does that mean I can use my gate pedal safely in the power amp serial loop?
Using an an online converter, +4dBu equals +1.78dBV, so I should be safe, right?
