Ahhh, the Pound Sterling...there's a definite reason why Britain is not on the Euro, LOL! Yes Bass World UK's prices are high, especially for one like me who has $USD, LOL! They do have an excellent selection, though...better than most US Dealers...and you do get what you pay for with an Alembic.
Further, unless you have one custom-made, they got the only two J-bass bodied Alembics currently available (only one left now) anywhere, to my knowledge. IMHO, Alembic seems to prefer to leave the Fender-clone business to Sadowksky and Lakland, so you probably won't see too many more like these, LOL!.
