My band does a mix of covers and some originals. As such, the covers range from Zeppelin to 90s grunge. My ideal "dream" tone is Helmet's "Unsung". I currently have a Darkglass VMT pedal which I really like but would like an add-on pedal to those songs where I need extra break up and grit. I currently have a great "mild" version of this with the VMT but want something to add to really put those Helmet, Tool, Filter songs into another level. I really am avoiding purchasing an SVT or V4B amp as I already have a TH500 which I have invested in an otherwise is a great amp. Any suggestions? B3K? VT bass? Barbershop?
