I got my Gedo bass direct from Gedo Musik in Germany. https://www.gedo-musik.de/
Here is something with the bass on from a few months ago. I think the bass cost about £1300. I changed the strings and bridge early on but that's all. Mail order took a few days. Bass solo around 4.50 mark for a more isolated sound. Apologies for the iffy intonation but that is not the bass's fault.
Peripheral but interesting.
I decided fairly recently try to learn to read guitar music. I am nearly 55. I have made incremental progress to the point where last week, I bought a book of easy classical guitar pieces. I have since read 85 short pieces of music cold, including notated chords. It's really exciting.
Here we go. I have a reputation as the Jazz aficionado on here but here is something else I do that is a little different to the normal 'random noodlings'. Features Tim Ainslie on guitar and Brendan O'Neil on drums (Brendan played with Rory Gallagher for 10 years).
There are plenty of garden building firms who can put something up for you. I guess it depends on your budget as to what you want to spend. My cabin was about £1600 and then a bit more to have power installed. I know people who have spent considerably more but it depends on the size you need, soundproofing, security etc. most of which will be a personal choice.
I love the idea of sitting in there playing flamenco guitar, Shaggy. I sit an play my Ovation Custom Legend in mine, working on my guitar reading, and am in heaven. It's nice not to have to plug things in and set up amps and stuff.
No insulation and no ill effects on gear. Guitars, PC, effects, saxophone, books, cds, art etc. The wood is s natural insulator and absorbs moisture thereby preventing damp of any kind. I have a carpet in there and it is not showing any signs of deterioration. Would recommend wholeheartedly.
I have a wooden cabin and find it more than satisfactory. Too hot/cold is managed by a fan and a heater. Otherwise, it is dry and I see no evidence of condensation after 4 years. Mine is a tiny bit too small at 8x10 feet but I have a PC, double bass, two electrics and five guitars in there as well as books and cds. No problem. Cost about £1600
At the moment, it's Ralph Towner because I am working on becoming self sufficient as a composer and performer and he has that down to a fine art. His choice of instruments is also eclectic and he can play simple things alongside intensely complex compositions. like everyone else, though, my influences are many and varied and always transitory.
I saw Gordon Giltrap last night and he played one of those Paul Brett Vintage Viator travel guitars. It sounded beautiful. I am gassing for the 12 string version now.
I have some very personal theories about the relationship between tone and swing that I discuss in my Paul Chambers biography. In short, imagine what Kind of Blue would have sounded like with BS's tone heard here. Not wrong but starkly different.
