we plug the 22 into all sorts of cab sizes and it is just ridiculous though a 4×12!
what kind of noise is it? a loud hum? can you still talk into the mic and hear anything?
hey Diego,
regarding the gating noise, most analog delays feature some kind of circuitry to minimize noise. the DXMB has similar circuitry. however the effect is most prominent on the first note you play after a long silence, so your 2nd and 3rd notes etc… should not sound as gated as the first.
i’ve heard of some people putting eq’s in the feedback loop to tailor the wet sound a little more, might be worth a try.
have you tried any other pedals in the loop to see if it makes the same pop?
regarding the low cut feedback. when you turn up the low cut, you are decreasing the overall signal getting fed back. you can adjust for this by turning the blend up a little, and turning up the gain a bit.
does the mic require phantom power?
when the iron lung is on, are you testing the the guitar, and the microphone separately? if so, try singing and playing the guitar at the same time.
