Key Points

Lichtlaerm Audio's Lennart Bossu Signature "Thorn" is a compact 3‑mode high‑gain distortion. Lennart Bossu (Amenra, Living Gate, Oathbreaker, Predatory Void) inspired a shrunken take on the Providence Stampede SDT‑1. First batch sold out on EvilGreed.com; second batch is available at Joe's Pedals (UK).

Modes: SDT‑1; SDT‑2 (more compressed/saturated, some volume drop); Laerm (more open, louder). Controls: Gain, additive Boost, Level, Treble/Mids/Bass, EQ, MODE and footswitches.

As of 2025, the price was £199 at Joe's Pedals (UK); Licthlaerm EU lists €229. Thorn is the fourth Lichtlaerm high‑gain after Altar, Gehenna, Medusa; closest to Gehenna. For servicing consult a qualified tech.

Readers should know that I’ve long lauded Lichtlaerm’s previously High Gain Trifecta - the Altar, Gehenna, and Medusa. And now we have the 4th killer compact candidate to join that elite!

I believe the first batch (which sold out very quickly!) was only available on the EvilGreed.Com Webstore - while the second batch is more widely available, including at Joe’s Pedals in the UK - where indeed I got mine from.

Lennart Bossu, of Amenra, Living Gate, Oathbreaker and Predatory Void bands - used to deploy the fairly large format Providence Stampede SDT-1 pedal - where Daniel of Licthtlaerm Audio has expanded on that circuit and shrunk it down to a more potent compact format.

The ’Thorn’ has 3 modes onboard, the Stock SDT-1 core sound, then a more Compressed and Saturated SDT-2 (which also has some volume drop), and then the more open and even louder new ’Laerm’ mode which seems to be my favourite! I mostly live on the original STD-1 and new Laerm Modes.

This is such a potent distortion, I really don’t feel I need the Boost at all - that slightly tightens up the delivery and adds more sustain - while I really feel that I don’t need it!

Controls - Gain, Boost, Level, Treble, Mids, Bass, EQ : Off / On, MODE : SDT-2 / Laerm / SDT-1, Boost Footswitch, Bypass Footswitch.

The Boost on this occasion is additive rather than independent, and as I already said - I never feel that I need to deploy that.

My favourite setting have Gain, Boost, and Level all @ 3 o’c (Boost mostly off!), then Treble @ Max, Mids @ 10:30 o’c, and Bass @ 3 o’c. I much prefer the EQ On! And I much prefer the SDT-1 and Laerm Modes over the SDT-2.

This is a really easy pedal to dial in - yielding instant satisfaction. Shame it didn't happen in time for my recent Full Metal Racket article - as it would for sure have had a place there.

I reacted way too slow on the first batch - and those pedals were entirely sold out by the time I got to them. So I'm glad to have finally snagged one - in time for the 2025 end of year roundup!

The Lennart Bossu 'Thorn' is now widely available including at Joe's Pedals in the UK - £199, and Licthlaerm in the EU - €229, it has yet to appear at Eastside Music Supply.

All 4 of my Lichtlaerm High Gain Pedals are pretty distinct - this Thorn is closest to the Gehenna - but there are still distinct differences between them. I'm very glad I have both as each hits somewhat differently!

I don't feel I will ever be disappointed with a Lihctlaerm Audio pedal - all 7 of the ones I have to date sound superb - and I still have a few further targets!

As I said in my recent Full Metal Racket - it's mostly just 3 brands that are really pushing the next generation of High Gain Pedals - Fortin, Lichlaerm, and Sinvertek - those 3 never fail to impress! I've not had as much experience of This Heavy Earth - but feel that may well belong in the same group!

The Thorn is another fantastic High Gain variant - highly recommended!

I probably also need to get the mid-size Total Distortion Workshop MKII - to complete my Lictlaerm High Gain collection. Obviously I lean somewhat more into compact formats as hey are more flexibly accommodated on the board!
