Topic: Lightening the Load! |

In a quest to have the most manageable load-in but the most play-ability on stage, I've gotten my total equipment weight to 126 lbs. This is with my Rains D-10 8+8, SteelSeat Lite with cables,strings and two Emmons Volume pedals and my Nashville 400 with TT 12" speaker!
The first step was the steel gig bag( see "Legrande Gig Bag Deconstructed")BTW after 5 years, the zipper is failing so I ordered a new one $35.
The latest development was making a Peavey Nashville 400(my amp of choice) lighter. After using a light-weight Neo speaker what else could I do but build a light cabinet. I tried a Peavey 130 Special cabinet(empty weight-18#) which turned out 3#s heavier than my silver cornered stock 400 cabinet. With the Special cabinet as a template I built a pine cabinet(15#) and finally a Paulownia cabinet (empty-7#s). Paulownia is 1/2 the weight of pine but the same strength, although it is hard to find for sale.

Cool tip about the Paulownia wood. Woodcraft stores say they stock it when available, although none shows in inventory at the time.
I also was curious about your gig bag arrangement, so I dug up your original post on that. I'll looking into that and I'm sure it will be interesting and helpful to others as well. Thanks John.

| Nice “lighter†rig. What’s the 1/4†jumper on the rear? Been a long time since I owned a Nashville.... |

| Kevin, the jumper just makes sure those in/out jacks don't distort the signal. |

Brilliant fix for the intermittent jacks!
Any comments on the TT-12 versus the Black Widow or any other speaker? I've got one on order. |

John, I also use a carry bag for my pedal rack, rods and legs. Bought the bag at Academy Sports. It really does lighten the load.

What did the total weight of the amp come out to be?
Did the new lightweight cabinet change the sound at all?
BTW, that is a very nice looking cabinet! |

| The Nashville 400 with TT speaker weighs 36#, I think the sound stayed about the same. I played it at the last Southern Steel Guitar Convention in November and got plenty of compliments ! |

Hi John,could you and Greg maybe explain a little bit on what that 1/4"jumper does for the
Amp,that's interesting ,thanks!

John - That amp looks great! I'm glad you left the ugly (IMHO) logo off the front.

| Larry, those jacks are notorious for getting corroded and having your signal break up.Russ Hicks pointed out by using a jumper you negate the problem. |

looks great John let me borrow the amp for a year and I'll let you know if the weight is better !

John, nice upgrade of a great steel amp!
I'm another fan of soft cases. Original hard case was 25 pounds, empty. Soft case with Carter SD-10 body ~23 pounds.
Case #2 with legs, rods, cables, VP ~25 pounds.
The 15" EVM makes this LTD-400 a beast. How much lighter would it be with new 4-ohm Eminence Double-T/15?

Dan, I have an 15"EVM,great speaker very smooth. I think it weighs an out 19#, the TT will be about 8#.
Greg, the TT 12" is smooth without the harshness of the EPS 12". I've never owned a 12" BW. |

I think you have some fantastic ideas!! Where did you get the Paulownia wood, and in what sizes?

Thanks, John.
Mike Scaggs and friends compared the TT/12 and a TT/15 prototype:
https://bb.steelguitarforum.com/viewtopic.php?t=327238
Not much difference in weight, both are 7 pounds and change:
https://www.youtube.com/watch?v=R0b7qUPPKwI&t=26s
IIRC the Double-T/15 will be 4 ohms. Drop in upgrade for the LTD-400, no baffle change needed. That's what I'll do if I hang onto it. It needs a "senior center" tune-up 
I like the soft case you use for your LeGrande legs/pedal-bar. Gonna get one.
Thanks again for the great info! |

Pawlonia is light but not NEARLY as strong as pine! I've used in in 6-string construction to build cheap "kid" guitars and test cabinets, but it's rarely used for anything where durability may be an issue. Having fairly wide experience with it I'd never use it for a gigging cabinet of any kind.
If you look up wood hardness charts Pawlonia is the second softest commonly-found wood. It's very prone to denting and screws must be used very carefully, as stripping is a major problem.
http://www.wood-database.com/wood-articles/top-ten-softest-woods/
Pawlonia's hardness is 260 lb/f - most pine species are at least *double* that.
Things I'd recommend when using Pawlonia - No screw connections (through-bolts only); speakers also need to be mounted with through-bolts. T-bolts will eventually loosen due to poor crush and lateral tear strength, with vibration/weight widening and weakening mounting areas;); No finger joint for the same reasons; glue joints must be reinforced with dowels or bolts.
Finishing is a non-issue - coatings are easily damaged; n commercial parts polyesters are used almost like an "eggshell" but are easily dented. The only options are tolerating visible damage or covering with fabric (or tolex) and tolerating the dents.
My biggest concern - and what I'd keep a VERY close eye one - is the speaker mounts loosening due to vibration. Even with through-bolts the bolt holes *will* open up over time and the speaker will vibrate more and more; wood damage will increase as this happens (note "will" - not "might".)
Having worked with this wood quite a bit I seriously recommend rethinking its use for a cabinet. It will fail, and if it happens mid-gig...and if you don't carry a backup, which sounds unlikely...you'll end up with a serious problem.
To me it's not nearly worth the slight weight reduction over pine. You couldn't give me a Pawlonia speaker cabinet - seriously. I couldn't trust it to hold up for even a short time.
I just hope I can save you a big headache.

| I've noted your concerns Jim, but I think for this size and weight cabinet they're non-issues. Forty years of woodworking has given me some experience. I would never suggest Paulownia for a kitchen table or flooring, but looking at several databases it's 60-70% as hard as the white pine Lowes sells and I expect it to get dented eventually. That said, Paulownia is impact and split resistant, which is why it is used for Surfboards! The 7# speaker is mounted to a 1/2" plywood baffle with tee-nuts. The baffle is attached to supports,that are glued and nailed to the side panels, with drywall screws. If this fails over time, I would replace the supports with pine or something more durable. I feel in my circumstances weight is more important than durability ! Keep in mind this is a 20" wide cabinet weighing 36#. YMMV, Respectfully JS |

Makes more sense with the baffle arrangement you describe for sure.
But I would hardly call Pawlonia "impact resistant" based on the number of refused requests I've had to "fix the finishes" on dented Pawlonia bodies. I tested a couple myself, with rubber mallet easily denting one - and the other pressed in (through the polyurethane "shell" finish) with an elbow. And I don't weight all that much!

| As I said Jim, they build surfboards out of this and they take a lot of abuse. Fender even had a line of lightweight solid bodies made with Paulownia. That said, I don't care about dents and finish cracks, I'm only interested in weight and sound. |

I put a Neo 15" in my 400 recently. It helped a lot, but it's still very heavy.
Does anyone make a lighter transformer replacement? Because that thing is heavy... |
