Well, first of all, sorry for my english, I'm a french guy. Then, in my quest of the great and affordable amplication I've found 3 cheap all-tubes heads (between 300 and 700 Euros) : The Pignose B-100VH, the Sovtek MIG-50 and the Sovtek MIG-100 : Pignose - B-100VH : It's a 100 W head with four 6L6s tubes and two 12AX7s tubes. I've never heard about this brands, that's why I'm a little bit affraid. The reviews on internet are pretty rare, but they are all positive. Pignose : www.pignose.com Sovtek Bassov Blues Midget (MIG 50B) : It's a 50 W head, with two 5881s for the power amp and one 12AX7WA and one 12AX7WB for the preamp. I know that Sovtek is famous for it tubes production, and also in the construction of the Russian version of the Electro Harmonix pedals. But about the amps... ? And 50 watts, even with an all-tubes head, is it sufficient to play among a drummer, a singer and an overdriven guitar? Sovtek : www.sovtek.com Sovtek Bassov Blues Boy (MIG 100B) : This is the MIG 50B's elder sister. We should feel more comfortable with 100 Watts. It works with three 12AX7s and with four 5881s. The reviews found on internet are numerous and very positive. Sovtek : www.sovtek.com Now, I would want you advise about them. Ok, they're all-tubes and cheap, but do they sound great? If not, I prefer to buy a solid one or hybrid combo. Thanks in advance, and may the groove be with you!
