    Deluxe

    Complete and rather flexible, but it is not convincing. Perhaps, the problem is the 12" Special Design Eminence. The footswitch is included.

  • Laney
    VC15

    A perfect solution for who is looking for a quality product, but transportable. Two different inputs, but the equalization section is common. A dedicated output for an external cabinet.

  • Fender
    Pro Junior

    Small but beautiful. Simple but flexible. The clean is full and smooth. The distortion is a masterpiece. Warm, full of harmonics, with a great character. The simplicity is the added value.
