Neil's pine PP-18 head

By far the simplest way to make a head cabinet is to use pine. It's a softwood, so it's easy to cut and work, but you won't get the same resistance to wear and tear as tolex. Still, the world's full of old pine furniture, so it can't be that bad. Neil's given the pine on his PP-18 an antique pine finish, and the knots add to the charm.

Tim's PP-18 head

Here's the same 18W amp kit in small-stack form. The cab is a 1x12 and Tim's used the same grille cloth for the head's front panel. This helps to create a much more modern look.

Daniel's PP-18

"In one sentence, it's... very 'evy, very 'umble; very purple, very loud." I've lived in the UAE myself, and still can't believe that Daniel managed to round up the cabinet materials out there. "The purple tolex is from a fabric shop in Abu Dhabi - it was really meant for covering bedroom furniture. The grille came from a waste basket, and the wooden case was made by a guy who claims to be a carpenter but took two goes to get it right." Commendably resourceful!

Dominic's PP-18 pair

Some guitarists really love the 18Wer's tone. Dominic must be one of the biggest fans: "Have built three PP-18s now, all sounding amazing by the way! Two now live in a custom flightcase, looks nearly as good as they sound!"

Harvey Brades' '50s flashback

"Will send some pictures, guaranteed you will be impressed," said Harvey's email. He wasn't wrong: this retro cabinet is as wonderful as it is crazy. The 18W circuit was borne out of the '50s WEM Dominator circuit, so this combo design is very appropriate. Can't imagine how tricky that was to plan, cut and glue.

And I love the rear view almost as much as the front.

Howard's two-tone PP-18

Burgundy and cream is one of those colour schemes that always looks classy, as in this rexine-covered head cabinet. Especially like the double ventilation slots at the rear. "Finished the amp end of last summer, have built a matching 2x12 cab to go with it."

Steve Wilkins' PP-18 walks the plank

Pine is a popular choice for cabinet builders - easily available, soft to cut and easy to shape. Steve's plank-based crate must be one of the most... er... simple to build of all.

Jonas Broman's PP-18

Jonas has completed his 18W amp in both PP-18 and SL-18 forms. "The cabinet (inspired by the Marshall smallbox) was built by myself using MDF from the local shop and tolex etc mostly from Tube Amp Doctor. I also designed the logo (using the early '60s Marshall block logo as inspiration) and ordered it from http://skyltmax.se/ (in Swedish, sorry). I am planning to make one more similar cabinet, but with black tolex."

Jyrki Saarela's tweaked, untweaked and tweaked again PP-18

At http://www.18watt.com there are several simple gain mods for the 18W circuit. Jyrki had tried one of these: "I also modified circuitry a little, now the first triode is boosting the second stage. It still cleans up with guitar's volume control, but does Iron Maiden at heavier end." This does change the dynamic response of the amp, however: "I ended up undoing the gain boost job. I'm happier with the basic grind and still can use whatever pedal needed for heavier stuff. Some things just should be left alone."

Since then, Jyrki's added a half-power switch (to be covered in a future article) and a built-in L-pad attenuator. "Oh, by the way, I did a gig with the amp 2 weeks ago. It was actually our fourth gig And it seems that it will be my main gigging amp for the foreseeable future. Managed nicely unmiked in small pub, at half power and a little bit of attenuation."

Jef Grainger's Dumb Blonde

"Really pleased with the result! Christened her the 'Dumb Blonde' due to her modest complement of knobs! The Cab is one of Chris', in ivory tolex. Superb finish. I added a custom handle as I've never liked the Marshall-style ones. Panel text is by inkjet water-slide transfers, and the cab logo is a water-slide transfer reversed under a 2mm perspex plate. Would love to have been able to get the panel text behind the plexi too, but that would have been a whole new chassis plate... By the way, that Two-Rock 2x12 cab is as boutique as they come. You should hear the amp through it.... lordy!"
