This is a very rare TECAMP PUMA 900 bass amp head. I used it once in a studio after purchasing it. It weighs 1.49 kg and is a high-power amplifier with an output of 900W. There is no scratchiness in the knobs, and it comes with a dedicated case, instruction manual, and adapter. The condition is a beautiful item with little use, but please consider it as a used item. Due to the prevention of replacement, no returns or exchanges are accepted. The following is a description: Lightweight amplifiers are one of the recent trends in the bass amp market, with many manufacturers competing to release them. However, the amplifiers made by the German company Tecamp are not only reliant on high-end parts and the excellence of digital amplifiers. Instead, they are the result of Thomas Eich, the manufacturer and bass player, building everything based on the standard of what constitutes a good quality bass sound in an ensemble. Therefore, this amplifier is free from the shortcomings often found in this style of amplifier, such as the feeling of insufficient output compared to the published value, and the lack of appeal that is even more pronounced in solid-state amplifiers without vacuum tubes. It is a lightweight amplifier with a sound character that is both heavy and lustrous, reminiscent of a tube amplifier. This is largely due to TecAmp's previous work in integrating excellent solid-state, tube, and digital amplifiers, and their deep understanding of the weaknesses in sound quality of portable, small amplifiers. The TecAmp Puma Series has none of the dissatisfaction felt with conventional lightweight amplifiers, and boasts sound quality that feels more than sufficient even when connected directly. At the same time, great consideration has been given to the ease of sound creation, and it is no exaggeration to say that it can cover all the tones that bass players generally look for in an amplifier, and it is also possible to send that information directly to a PA or mixer. The Puma 1000 boasts an unprecedented high output of 1000W in bridge mode with a weight of 2.8 kg, and the PUMA 900 boasts 900W with 1.49 kg. It can be said to be the completed form of bass amplifiers that have actively incorporated digital amplifiers and switching power supplies in recent years.
