What is reverb

• Wikipedia

X/Y bugs

If X/Y copying doesn't work, upgrade to firmware 1.05 or later.

Spillover

• Spillover of reverb/delay trails

Rev Mix

The Rev Mix parameter in the Global menu lets you boost or cut the Reverb Mix setting across all presets at once.

Room ambience

The Cab (block) has reverb controls for adding room ambience to the tone.

Maintaining unity gain

When using Mix to control the volume level of the Reverb, the volume level of the dry signal is affected also. In other words, when turning up the Reverb level, the dry signal's level decreases. To deal with this: turn up Mix to 50% and set Level to +6dB. Or put the Reverb in a parallel row, see Effect blocks: parallel rows.

Spring reverb

Firmware 3.00 improves the Spring reverb.

Firmware 7.00

• Firmware 7.00 release notes: "Improved Reverb block. The Reverb block has two new parameters: LF TIME and LF XOVER. LF TIME controls the decay time relative to mid-band. LF XOVER controls the crossover frequency to the low-frequency decay. Many real rooms have a longer low-frequency decay time relative to mid-band. These controls allow more natural reverb simulations. The Types in the Reverb block have been reworked due to the new algorithms. As such, for best results you should reset the Reverb block by deselecting and then reselecting the desired type."

Delay before reverb or vice versa

• Cliff: " If there isn't distortion or modulation in the delay/reverb then the order is irrelevant since they are then Linear Time Invariant (or shift invariant in digital parlance). If there is a small amount of distortion or modulation then the order is probably still irrelevant. If there is a lot of distortion or modulation then the order may make a difference. However, typically the biggest difference, as noted above, is series vs. parallel since h1(t)*h2(t) is not the same as h1(t)+h2(t). If LTI h1*h2 = h2*h1. It may seem counter-intuitive that the order doesn't matter but try it and you'll be surprised." Source
