15-Watt Tube Combo for Guitarists

This 15-watt all-tube combo amplifier uses two EL84 power tubes and three 12AX7 preamp tubes. It is built for guitarists who want genuine tube overdrive and clean headroom at manageable stage or studio volumes. The 1-watt mode allows quieter practice without losing the characteristic tube response.

Celestion Speaker and Spring Reverb

A Celestion Seventy 80 12-inch speaker handles the output, delivering a focused midrange that suits many musical styles. The genuine spring reverb tank adds depth and ambience, controllable via an optional footswitch. An effects loop and external cabinet output provide routing flexibility for pedals or larger speaker cabinets.

Check Tube Compatibility and Footswitch Needs

Verify that your existing footswitch uses a compatible latching or momentary switch type for the reverb control. Ensure you have access to replacement EL84 and 12AX7 tubes for future maintenance. Confirm the external cabinet output impedance matches any extension cabinet you plan to connect.

Questions about this item

Does the 15-watt tube section stay clean at stage volume?

The 15-watt EL84 power stage delivers usable clean headroom for small venues; engaging the 1-watt mode reduces output for home practice without losing tube character.

What speaker cut-out and baffle depth does the 1x12 Celestion Seventy 80 require?

The amp ships as a sealed combo with the 12-inch Celestion Seventy 80 already mounted, so no separate speaker cut-out or baffle measurement is needed.

How do I connect the footswitch for the spring reverb without losing the effect loop?

Plug the supplied footswitch into the dedicated reverb jack on the rear panel; the series FX loop remains independent and can be used simultaneously with the reverb engaged.
