Just got mine. I can't say I have enough bottom in mine, so I swapped out the V30 (only had one in it, the other was a Celestion G12M-70 that I pulled even before hearing it). I now have 2 WGS British Leads in it. I am so accustomed to open back cabs, that I think I will make a partial open back panel for mine. The jury is still out until I get to hear it an an appropriate volume. Even when it comes to speakers, tone is still subjective.
