About the Tweed Champ Style Amp kit:

Mojotone’s Tweed Champ Style Amp Kit is based on the beloved 5 watt amp from the 1950s.  These amps were perfect for recording and were featured on a wide array of recordings from Joe Walsh’s “Rocky Mountain Way” all the way to Derek & the Dominos’ “Layla.”  Modeled after the historic Class-A 6V6 platform, this amp delivers warm tones that are harmonically rich and have a beautiful low volume crunch.

The amp utilizes one 6V6 power tube and one 12AX7 preamp tube, giving the amp its famed lush harmonic composition.

Don’t be fooled by the fact that this circuit features only a single volume control; 5F1s have been used by some of the greatest guitarists and on some of the greatest recordings of all time.  The Tweed Champ style amplifier is extremely tactile and responds well to dynamic playing; so no matter if you play jazz, classic rock, blues or anything in between, you will not be disappointed.

About the Deluxe Style Amp:

Mojotone’s Tweed Deluxe Style Amp is based on the popular 5E3 circuit from the 1950s and is a very popular amplifier.  These amps were originally designed as medium power amps that would allow a musician to plug in more than one amplified instrument at a time.  At higher volumes, this amp produces saturated tones that were adopted as signature tones for the likes of Billy Gibbons, Neil Young, Don Felder, and Larry Carlton.

Utilizing two 6V6 power tubes, one 12AY7 preamp tube, and one 12AX7 preamp tube, the circuit is simple enough to maintain a rich harmonic composition but powerful enough for guitarists to use in recording studios, rehearsals and smaller venues — and the amp is just a microphone away from being ready for bigger stages.  It sports a Jensen C12Q 35 Watt speaker to complement the 5E3 style circuit, as it enhances the sound of the amp without compromising its historic tonal accuracy.

The Tweed Deluxe style amp has two normal channel inputs and two bright channel inputs.  The normal and bright channels each have their own volume control, and the two channels can even be ‘jumpered’ together and blended for a new range of tonal options.  The global tone control also helps shape the overall timbre of the amp, giving the player total control over their sound without having to spend hours dialing in EQs.
