Case in point, the short lived solid body Epiphone Del Rey model was modeled after a Gibson Les Paul double cut. Workmanship and manufacturing standards were so high that Gibson killed the model. To help distinguish itself from the parent brand, Epiphone also maintains its own line of archtop guitars and basses. As of January 2013, Epiphone makes the following guitars:    Epiphone began producing amplifiers in 1935 with the Electar Hawaiian Lap Steel Guitar Outfit. This outfit was an amplifier, case and lap steel guitar stand all rolled into one unit and was supplied by a suitcase manufacturer of the time. Gibson produced Epiphone amplifiers in the 1960s. These were basically copies or variations of Gibson and Fender amplifiers. They used a tube design, and some had reverb and tremolo. Gibson decided to launch a new line of Epiphone amplifiers in 2005 with many different models, including the "So Cal," "Blues Custom," and the "Epiphone Valve Junior". The Valve Hot Rod and Valve Senior were released in 2009. The Valve Hot Rod is a 5 watt amp like the Valve Junior, but has a gain and reverb control. The Valve Senior offers 20 watts of power, with a full equalizer, gain, volume, reverb, and presence control. As of 2012, Epiphone has ceased production of their line of amplifiers with the exception of the Player and Performance Pack practice amplifiers, available only in Epiphone's starter packages. These Amplifiers are under the Epiphone Electar moniker. Epiphone instruments made between 1957 and 1970 were made beside the Gibson factory at 224 Parsons (Gibson located at 225 Parsons) St and on Elenor St; Kalamazoo, MI 49007. Solid body guitars with flat tops and backs were made at the Elenor Street plants (both Gibson and Epiphone) in Kalamazoo, Michigan. Some of these Epiphone instruments were effectively identical to the relevant Gibson versions, perhaps made with same timber, materials and components as the contemporary equivalent Gibson guitars. Epiphone also continued its production of world class archtop guitars using the same patterns and molds from Epi's New York era. Some specific examples of Gibson-era Epiphone instruments from this period includes the Epiphone Sheraton (co-developed with the Gibson ES-335 & sharing its semi-hollow body, but with, Epiphone's pre-Gibson "Frequensator" tailpiece and "New York" mini-humbucker pickups, and significantly fancier inlays) and Sheraton II (replacing the Frequensator with Gibson's "stop-bar" tailpiece), the Epiphone Casino (similar to the Gibson ES-330), the Epiphone Caballero (similar to the Gibson LG-0), the Epiphone Cortez (similar to the Gibson LG-2), the Epiphone Olympic Special (similar to the Gibson Melody Maker), the Epiphone Sorrento (similar to the Gibson ES-125TC, except for a few cosmetic changes), and the Epiphone Texan (similar to the Gibson J-45, apart from a change in scale-length).
