Decided Central London was a place to escape today, took all of the stuff up to a friend's practice space early this morning (borrowed a friend's estate car). Did some bi- amping experimentation, wound the amp output down a bit on one of his nice guitar cabs for the highs. Also did the 4 bass cabs thing on split full range. Holy Moly that is more than 500 watts, think I might have bruised Kidneys! His Rickenbacker sounded so good along with his nice Jaguar. However my Sire M2 more than held its own, those pickups and pre amp kick out some output (needed to wind the gain back). My KSD 5er (Audere Pre) with new d'Addario Tapewounds sounds simply massive. Thank you for the Amp sir. Have just put in a bid on a Laney N115, moving the Trace 1818 is rather a trial!
