Ooh yes, yes, yes. I’ve used a variety of Trace heads through various BF cabs and they’ve all sounded immense.
The oldest head is a MKIV AH250 but the combination I’ve used most is an AH250 SMX with a Super 12 and then later a Super Twin. Great sound and dispersion but I’ve now moved on to the BF tens in the form of a Four10 and Two10. I prefer the coloured sound of the tens as it’s nearer the sound I have in my head. Haven’t been able to use these in anger over the past 2/3 years, but I’m very much looking forward to it when the time comes.
