I'm not great at tweaking EQs but when I hear my ac30 dimed, I hear alot of midrange bark. Bass frequencies are kind of subdued, and the high end stays sharp. The important mojo comes from the really poppy mids though.

What are you trying to make sound like an AC30? The problem with just looking at the EQ side of the equation is that the AC30 has a kind of weird amalgam of engineering compromises that result in a peculiar kind of harmonic and dynamic response. For example, it's underfiltered and cathode biased, so it can be spongy and has quite a bit of compression and sustain. OTOH, it uses a GZ34 rectifier, overspec'd for the output section, so that it has a fairly firm attack for a cathode biased amp. The underfiltering results in ghost notes in the mid-neck region of the guitar. The blue speakers give a fairly smooth breakup, with some upper midrange bark compared to American amps. Most people think that emulating a Marshall with EQ and an american amp isn't TOO hard, but a Vox sounds like almost nothing else (the Gabriel Voxer and a few other handmade amps can get close). You might find using a modeller a better way to approach this?

Thanks for your responses. I actually use a hayseed and a goodsell so they are pretty voxy to begin with. I use blues on all of them.
However, I hear on a lot of records (all of Peter Buck's work with Robyn Hitchcock, some Radiohead) a bit more of a midrange dimension than I am getting. I did change my preamp tubes to Dutch Amperex which actually made a difference in the midrange compared to the mullards I was using. I actually like dutch tubes better than brits :)
The guitars I use are a Rick Kelly bowery pine esquire, a rick 370 12 string with toasters, a 72 les paul special '55 reissue with p90s and a heritage 535 with lollars.
So, the sound I am hearing is similiar to the sound of a half open wah but not is upfront and nasally. Which frequency range would get me there? I cant tell if it is going to be greater than or less than 1k. Thanks for everyones help!!
