I was wondering what speakers others are using/found to work well with a Matchlesss. I noticed alot of boutique and Fender type amp owners swap out their speakers with their favorite types of speakers. Do Matchless owners do the same or are the 'specially modified' Celestions doing the trick for you? I had read one article where Mark Sampson said he tried out a bunch of different speakers and put alot of time into choosing the right speaker. Agreed or given all the new speakers on the market now, are people finding a better speaker(s)? Thanks.
