andyonbass Posted December 14, 2014 Share Posted December 14, 2014 (edited) Reluctantly up for sale is my ATS LBA500 amplifier head. This is a great 2 channel lightweight head with great tonal options and is ideal if you want to double up on double bass and electric, or fretless and fretted for example. Channel one features a semi-parametric eq section, which is ideal for your bass guitar, and the second channel is completely transparent with no tonal colouring, similar to high end hifi systems. I have been using this channel to amplify my double bass, and you really do get "my bass only louder" with this. Of course you can plug in via your preamp if your pickup requires it. You can also plug your iPod into this channel and us it as a practice tool, playing along with your bass plugged into the other channel, as both channels can be used simultaneously, which is not always the case with 2 channel amps. This is a warm sounding amp, with a wide range of tones available, a small adjustment goes a long way with the eq controls on this. Weighs 1.9kg - about the same as two bags of sugar! Its got tall feet, which means it'll sit over the top of the handle of cabs like Barefaced or similar 500w @ 4ohms, 250w @ 8ohms. Comes with a neat little carry case which would cost you £70 to buy as an accessory. So if you're wondering what to spend your Christmas bonus on, here is a great sounding multi-use amp head for £399 plus insured postage of a tenner. Not looking for trades at this time, sorry Specs [url="http://www.atsitaly.it/images/ats_documenti/LBA5_brochure_english.pdf"]Here[/url] Website blurb.. [i][size=4][font=Helvetica]The LBA-5 is an amplifier designed to obtain very high audio performances in a small space and weight. As a matter of fact it provides 500 watts of power (RMS on 4 ohm) and it weighs only 1.9 Kg. [/font][/size][/i] [i][size=4][font=Helvetica]The preamp stage is realized with MOSFET discrete components, but it has the warm and mellow sound typical of the tubes preamp (in particular of the triodes). Furthermore it is equipped with a semi-parametric control on the mid band, with an asymmetric control on the high band and the original Contour control. [/font][/size][/i] [i][size=4][font=Helvetica]Concerning the tone control, it uses also the technique of the frequency shift. Using this technique when the tone control works in exaltation it uses a different frequency (for example, on the high band, 6 kHz) than that one used in attenuation (on the high band 4 kHz). In this way the tone control is more effective in finding all the harmonic shades in the sound of the instrument. [/font][/size][/i] [i][size=4][font=Helvetica]Another important innovation in this head is the “contour control”, very different from the other similar systems available in the market. As a matter of fact it works with the central zero because in this way, when it works in exaltation (Max +15dB), it brings out the low and high bands, attenuating the middle frequencies. While in attenuation it works exactly in the opposite way. [/font][/size][/i] [i][size=4][font=Helvetica]Furthermore the LBA-5 it is supplied with a special input (INPUT 2 AUX), totally flat. Using this input it is possible to amplify a second instrument or another sound source like a a CD player, a PC, or a Mixer, etc. (useful, for example, for the players that need to play with a backing track) [/font][/size][/i] [i][size=4][font=Helvetica]The sound of the LBA-5 is warm and full-bodied, very different from the typical one of the class D amplifiers, usually “cold” and too much “dry”. [/font][/size][/i] [i][size=4][font=Helvetica]This LBA-5 can be considered a valid alternative to those amplifiers with only a single tube in the input stage.

andyonbass Posted December 16, 2014 Author Share Posted December 16, 2014 Did a rehearsal using this with my fretless AGC last night and it really makes it sing!! The new model is around £900 so this has to be the bargain of year!! Any trial welcome if you're anywhere near Swindon Link to comment Share on other sites More sharing options...
