Supro S6420+ 1x15 Supercharged Thunderbolt PlusThe Supro Thunderbolt Plus amplifier adds switchable power amp topology to the legendary 1964 Supro Thunderbolt, giving you the original 35 Watt Class A Cathode bias sound as well as beefy 45 Watt and 60 Watt Grid bias modes for additional headroom and tonal variation. This unique design is implemented via a three way selector switch on the front panel. Normal and Extra hot input options, combined with a wide range of available gain on tap, allow you

The Supro Thunderbolt Plus amplifier adds switchable power amp topology to the legendary 1964 Supro Thunderbolt, giving you the original 35-Watt “Class A” Cathode bias sound as well as beefy 45-Watt and 60-Watt Grid bias modes for additional headroom and tonal variation. This unique design is implemented via a three-way selector switch on the front panel.

Normal and Extra-hot input options, combined with a wide range of available gain on tap, allow you to fine-tune the texture and response of this amp’s massive sound. Turned all the way up, the Thunderbolt exhibits nearly zero self-noise, yet it puts out enough volume to be easily heard on large venue and theatre stages, with overdrive completely controlled by the guitar’s volume knob. The 35-Watt and 45-Watt modes both deliver the sag and bluster of the 5U4 tube rectifier while the 60-Watt mode uses a silicon rectifier to unleash maximum Thunderbolt power. The 60-Watt mode’s faster transient response and ample headroom is wonderful for pedals, and brings the Supro sound loud and clear to any size venue.

Massive custom transformers and lightweight, vintage-correct cabinetry--combined with the best sounding 15” guitar speaker money can buy--put the Thunderbolt in a class of its own. With the amp turned all the way up, chords ring with exceptional clarity and definition amidst copious amounts of tube overdrive and output-stage saturation. The variable power switching found in the Thunderbolt Plus model is an over-the-top hot-rod custom luxury guitar experience, decadently brought to you by Bruce Zinky and Dave Koltai.

Is this the one for you? It was for me!
Color: Black, Color: Black
Okay so if you are like me and shop last minute before a major event then this is perfect. I went through pages and pages on here to find a bag that let's be honest here will only be used once and put away. So I decided on this one because of the style and color as it will go perfectly with my emerald green dress that I am wearing to my bestie's son's wedding literally next month. The size is perfect and the quality is on point. Yes the bag is a little stiff when opening for the first time but if you plan to use this constantly then it should be more pliable over time. This will hold what I intend to take with me which is just the basics so the functionality will be great and the fact that it travels well is another point for this evening bag. Big value for the money and easy to use. If you like it buy it, if not find one that suits your needs and style and budget. This is a keeper.

Beware of the smell
Color: Black
Starting with the likes about this product: 1. Beautiful design 2. Large enough for my cell phone 3. Most important it matched my HEEZ Women's Ballet Flats Shoes Now for the dislikes: 1. The chemical smell coming from the bag was soooo strong my eyes watered and my nose burned just a little. There is no way I could carry this purse with out that smell wafting through the air. IT WAS THAT STRONG. 2. The flap was a little stiff to bend, so closing was a little hard to get it in position. I'm sure if you opened and closed it a few time it would loosen up. Bottom line I only gave it a 3 star because of the smell and I am retuning it. Not sure if you air out the bag for a few days if the smell would go away but I didn't want to risk it.

Love it
I really like this handbag. The pebbled leather texture looks elegant and feels good quality. It is small but still fits my daily essentials like phone, wallet, and keys. The top handle gives a classy look, and the adjustable strap makes it easy to wear as a shoulder bag. The magnetic closure is convenient and easy to open and close. It looks stylish for both casual and dressy outfits. I am very happy with this bag.

Love everything about it!
Color: Brown
Absolutely love this bag! It’s real Leather! It’s soft and slouchy. Has MANY inside pockets which like because I carry a little bit of everything. Has plenty of room without being overly huge. I’m using the crossbody strap to keep the weight off my shoulder and my hands free. This is a good handbag…and I am picky! This is the 4th bag (brand) I have gone thru this year alone. I’m gonna stick with this one (brand) til it wears out.
