The Electro Acoustic Guitar - A Short List Of Items That Keep It Going

Electro acoustic guitar, electric guitar or acoustic guitar - regardless of what type you've got, you will still have to provide running repairs every so often. While I cannot imagine the original delta blues guitar players having anything besides their own old guitar along with the shirt on their back, these days it's a different story and there are specific things the time conscious and careful guitar player need within their toolkit to guarantee the playability is maintained and importantly any upkeep uses minimal time.

So if you don't have infinite time on your hands, or fancy keeping it real like those early pioneers of the guitar cause I'd say that you probably have to be carrying, or have access to the following things nearby to keep your trusty guitar in tip top shape: First off you ought to be carrying some strings in the gauge you like and for the guitars you're playing. So if you play an acoustic carry the right gauge strings and if you are playing an electric or electro acoustic guitar some suitable different strings will be required.

Next, you ought to be taking a look at a good multi-tool just like a Swiss army knife that has slot and Phillips head screwdrivers, pliers, diagonal cutters (great for emergency wire stripping) and a file for your fingernails!! For the price of them it may also be worth putting in a set of real diagonal cutters for trimming off changed strings. They work a bit more easily than the ones on the multi-tool. As you know it is sometimes surprising just how strong strings can be and these can certainly make light work of cutting the string after replacing.

For the ¼" nuts on jacks and effects pedals I have a smallish socket and hand driver because I notice they will undo regularly.

A smallish hand towel is helpful for quick care of kit. Specifically perspiration along with grime which rapidly builds up and quickly damages as well.

Extra picks you could store in a tobacco container together with any rogue screws, bolts and washers that often show up with no seeming point of source.

Something that is ignored could be extra 9v battery packs. They are utilised inside pedals as well as in a preamp in electric acoustic guitars and may wear out at some of the most inconvenient times.

I'd point out these will be the most essential things to have around when you are either at your home, rehearsing or gigging. In case you fancy some overkill then you may also go with these.

Tuning lubrication is fantastic for rubbing on brand new guitar strings when you change them. It puts a stop to them from busting when you're winding them on and also you could have some form of guitar string solution such as Fast Fret that will extend the useful lifetime of a guitar string and stops rust setting in.

Allen Keys in different (but relevant) sizes if your multi-tool does not have them are useful. These are particularly useful for anything around the pick-up area.

If you need to get your guitar restrung in quick time and you have given your roadie the night off try getting yourself a battery powered string winder. Make sure you carry spare batteries for it though, otherwise it will be pretty useless.

So, lots of things to remember if you want to make sure your electro acoustic guitaris in great condition, but don't forget the bag to keep it all in!!

Diy Stereo Bi-amplifiers?

hi i am quite new to audio amplifiers. I have previously build some guitar pedals and guitar preamp/powers amp.
So now i want to build stereo bi-amp with passive high-mid filter(chip or solid state).
Some this like this.

http://www.nmine.com/multiamp.htm

But this schematic is quite unclear to me. Any help will be appreicated. Or can you suggest any similar circuits with pcb layout.

Thanks

that's a strange way to draw a schematic. Basically it's a block diagram with detailed schematics on each blocks. So you have to look at the block diagram to see how to interconnect the pieces.

And, the values are not on the schematics, so you have to refer to the parts lists. Neither are the power connections to the ICs. Nor the bypass caps.

Basically, I'd take the drawings of the schematics, add the part values, and interconnect them as the block diagram shows, so you have one central schematic with everything on it.

But that's a bit of work, and you need a drawing application. And there may be other things missing that my quick look missed.

Edit, I can't find any heat sinks for the output stages, so this is capable of only a few watts of power, not very much.

Overall, there is a lot of risk to an attempt to duplicate this circuit, as too many needed details are missing.

VHT Special 6 Combo Amplifier, 6 Watts Review

Boutique amplifier players may take a quick liking to the VHT Special 6 Combo Amplifier. It is a handwired tube, with unique features and a great price tag. The Special 6 is mod-friendly and easy to customize, both for tube amp enthusiasts as well as home amp builders. It gets its powerful tube sound from the 12AX7 preamp tube and one 6V6 output tube.

The Special 6 features a footswitchable Gain Boost that will significantly expand its range of tones. By using the Gain Boost, players can quickly change between clean rhythm tones and overdriven leads, basically duplicating the functions of a footswitchable 2-channel amp, in a simple handwired, all-tube, 2-knob package.

To expand its range of tones, the Special 6 also comes with a High/Low power switch to enhance low-volume tones with an extra smoothness (when in half-power mode). It's a good feature when recording, or if you are simply practicing in your bedroom and need low volume. In high-power mode, it's one of the few amps in its class that is strong enough and loud enough to compete against a strong drummer. The Special VHT Special 6 Combo Amplifier is also outfitted with a high sensitivity 10" VHT Special Design speaker.

VHT Special 6 Combo Amplifier, 6 Watts Features:

* Power: 6 watts

* One 12AX7 Preamp Tube

* Footswitchable Boost Mode

* 4, 8, and 16 Ohm speaker jacks

* Mod-friendly eyelet-type board

* Dimensions: 18 x 20 x 12 inches

VHT Special 6 Combo Amplifier, 6 Watts Reviews:

Many of the reviews and comments that I have read indicate a strong favorable opinion of this amplifier from VHT. One reviewer stated that the new VHT company is really delivering some great amps at a great price. The Special 6 Combo Amplifier is good looking and hand wired, making it a great place to start for those who are changing from a solid state to a tube amplifier.

Another consumer who has played for quite awhile and has owned a good amount of high end gear, absolutely dislikes carrying heavy gear, and taking nice amps out. Also, a big concern with tube amps is the amount of abuse they may sustain when driving from gig to gig. The Special 6 is a great amp that fixes this.

It has great tone, and is very well constructed. Due to the price, the reviewer actually purchased two of them and they stated that when run simultaneously, these amps sound huge. There's enough headroom to run it clean, and get all your gain from your pedals. It seems to be great with pedals, and it was also mentioned that it even sounds very nice with a 10" speaker.

Their conclusion was to do yourself a favor. Pick up this amp if you have a chance, it will save your back as well as your bank account, because it's definitely worth the money. Other things said have been that it is an unbelievable value and it really delivers. It has a great overdrive sound, but yet it has a surprisingly sweet clean tone. The simple circuit makes swapping tubes interesting no doubt.

For the worst review of this amplifier, here is what was said. The consumer plugged in and the first thing they got was a shrill, thin sound. They replaced the stock tubes with an old Motorola 6V6 and a Groove Tube 12AX7. After this, the amplifier mellowed out. Unfortunately after about an hour of play it began to short out.

The speaker output jack is made of plastic and it had melted. The reviewer did say that it is better than most amps in the price range, but they wouldn't buy another one of these amps. The other thing that we found was that a different reviewer stated that the factory installed tubes sound ok, but you won't regret making the decision to install something better. However, the 10" speaker from the factory was generally well received.

With the nice amount of headroom this amplifier provides along with very high ratings from nearly every single reviewer, I will go ahead and give it my high recommendations. Plenty of strength and an overall very good buy.
