    Comments about Bugera 12AX7B Preamp Tube:

    I currently own 7 Bugera Amps. This is a stock replacement for all positions in each except for V1.

    I've put Tung Sol, JJ, Sovtek, and EH in and come back to these. It may be because it is what my amps shipped with and likely designed to use.

    Also another thing I like about Bugera tubes is that they all come with bubble wrap or foam around the tube inside the box.
    So if they are not packed well in shipping it doesn't seem to matter as they are already protected.

    Not for the V1 position

    Comments about Bugera 12AX7B Preamp Tube:

    In the V1 position of my JCM 2000 DSL, the distortion was over the top and unusable.
    I slipped it over into the V2 position and put an Electro Harmmonix(12AX7) into the V1 slot and, Voila!..... Classic Marshall sound! Crystal clear sound on all settings.
    And for reference.... I am using Tung-sol 12AU7,s in the V3 and V4 positions.
    Tonal Bliss!

    Comments about Bugera 12AX7B Preamp Tube:

    I play with a heavier tone (Les Paul Guitars with a Peavey Windsor Head - Think of Alice In Chains -HELMET Guitar Tones) I used this in the V3 position and lost clarity to the notes.It works good for my situation in the V2 spot.Lowered access noise and fattened up my Tone.I wouldn't recommend using this Tube in the beginning or final stages of you Pre-Amp section.I have a Sovtek in V1, this Tube in V2 and a Groove Tube in V3....Leading into 4 JJ KT77's.

        Comments about Bugera 12AX7B Preamp Tube:

        My preamp valves were failing on my Line 6 Sider II Valve after research I found that the correct replacements were 12AX7Bs ... these were the cheapest and most easily available. The change in sound has been a revelation - unfortunately not 100% for the better as it shows up how dire and artificial the Line 6 modeling really is .... as the amp is only ever used for practice it's not really an issue.
