Trinity Tramp


The Tramp began as a low-powered, practice-bedroom amp concept that turned into a full blown practice-home-studio-gigging amp. Why would we bother? There are lots of 2-tube amps out there, from the famous Fender Champ to the Epiphone Valve Jr, and many more. These amps have a sweet vibe but are challenged in what they can do; whether the amount of break-up they can provide in the case of some amps, or their tonal versatility in the case of others. The Tramp was designed to address this shortcoming and provide extreme versatility while still keeping to the format of a two-stage preamp and only two tubes. The Tramp also features a Master Volume control that doesn’t make the tone suck as you turn it down, as well as a variable power level control, allowing you to have almost any tone right down to bedroom volume levels you can comfortably talk over.

Sure am enjoying it. It's coming to it's first rehearsal today. It's the perfect size/power combo for me - I've never had an amp that I could run in the upper range all the time, nor one that sounds this sweet! It's a real treat. Thanks man

The Tramp design incorporates extreme, useful flexibility with distinct amp voices and plenty of features. With a simple pull of a switch, you can go from Tweed to ‘Tude; another pull switch and you can play Fat or Thin. Using the Volume, Master Volume and Power Level controls along with Bass and Treble, achieves tonal nirvana! The design supports 6V6 and most other octal power tubes so you can swap the single power tube for added gigging volume and headroom. Power output is approximately 6W with a 6V6, or 12W with the bigger tubes.

The Tramp is effectively two amps in one, which you can alternate between with the simple pull of a switch. It was intended to cover all the bases from Fender Clean to Marshall Dirty, and all the possible shades in-between – and it delivers an amazing tonal range in doing so.

In Tweed mode, it’s heritage is 3Fx series Tweed Princeton or Champ, with the additional benefit of Treble-Bass tone controls. Tweed is smooth and creamy with a welcome warmth, vintage voice but with a little more solidity and clarity. It is full of soul and you can really hear the Fender heritage. In Tweed mode, the Volume control is usable through it’s entire travel – gorgeous cleans around 5/6 on the dial, slight break-up around 7/8, and an amazing humming drive at 9/10. Everything you want in the classic Tweed amp spectrum, from clean to dirty, is right here.

In ‘Tude mode, the Tramp exceeds what you could traditionally achieve with the simple two-tube amp format. The sound opens up with an astonishing clarity, and extended range of clean and distorted sounds. ‘Tude glows with all of its harmonic content, and some Marshall crunch when the guitar gets wound up.

‘Harmonic haze’ is what it’s all about in the clean parts of ‘Tude – gorgeous! Just a little hair on the tone for presence with all these overtones swirling around it and a nice solid foundation. Cranked up, it’s complex, raw and edgy but still under control, and smooth but in an aggressive way – there’s tone right to the top. Using Fat or Thin settings doesn’t matter – it holds together but in a really primal raw “teeth gritting” way… with a P-90 Les Paul – it rocks in a Neil Young kind of way… Bass dimed, Bass at zero, it doesn’t matter. With big humbuckers driving it, and the Volume cranked right up, you get modern rock distortion tones. At the same time the natural tone of the guitar really comes through, and you get a completely different vibe from this amp between a Strat or an ESP.

With the Volume all the way up Power Level acts like a “presence” control – not in a “top end” sort of way, but more in a “brings the tone out of the speaker” wider, more comprehensive way. Because the tone is fairly compressed with Volume cranked, moving power from 10 to 5 on the power level doesn’t really make it much quieter, just darker and warmer, but still with all the beef.

As you increase the Tramp’s Power Level, the tone comes forward with highs and high mids becoming more prominent. At full power and bass down, you can get a real edgy, ringy, “transitory” kind of tone, and as you roll the bass up, Neil Young and his very large “tone” show up. With power level below 5 the tone gets quieter, but it still has all the rage. As an added bonus, players can switch back and forth from Tweed to ‘Tude without having to adjust the Treble or Bass – the tones just work without having to move a knob… so good news for those that dream of switching between Tweed/’Tude on a gig – you can just ‘Set it and forget it!’

The single-ended, unique design has many features but despite the nouveau circuitry; it is not housed in a trendy, all-metal lunchbox. The low-power addition to the Trinity line-up, is housed in a hand-crafted, finger jointed, pine cabinet, finished in a variety of coverings.


The single-ended design features a variable-level DC power supply and swappable output octal tubes for power stage distortion at a variety of volume levels. Utilizing one 12AX7 preamp tube, the design also supports one 6V6, 6L6, KT66, EL34, 6CA7 or KT77 power tube. Controls include Power On-Power Level, Volume/Tweed-‘Tude, Bass/Fat-Thin, Treble, Master Volume. The Tramp lives in a hand-crafted, finger jointed, pine cabinet, finished in a variety of coverings.

The Power On switch is incorporated in the Power Level control which adjusts the Trinity Amps Voltage Regulation Module (VRM). The VRM allows raging tones at volumes that guys who played in loud bands in the 70’s won’t be able to hear! The Volume control double as a gain control when in ‘Tude mode, and incorporates the Tweed / ‘Tude pull switch. There’s also the extremely effective Master Volume control.

Bass and Treble are subtle yet effective and sound great through their entire travel. The Bass control incorporates the Fat/Thin pull switch. Thin/Fat is especially useful. Thin is lean, clean and tight, Fat really thickenss things up and pushes a little more gain into the circuit. Both Thin/Fat work with any guitar – not only when you have to use Thin with a Les Paul because Fat is too fat, or you have to use Fat with a Tele because Thin is too strident. You get two different and useful options with every guitar.

All the controls do what you’d expect them to. But they also act as interactive tone controls. For example, use the Bass control in tandem with the Master Volume, or the Treble in tandem with the VRM. Increasing the Master Volume can bring up the bottom end of the tone, and increasing the VRM can add top end to the tone. This is one of the coolest parts of the amp because as you work these tandem controls in opposite directions, the treble/middle/bass relationships in the tone don’t change, but the tonal quality itself changes! And in the absence of a mid control, by changing the relationships between the tandem controls you can effectively control the midrange!
